Cows can sleep while standing up, but they only dream if they lie down.
Whales and dolphins are “conscious breathers,” and they need to keep breathing while they sleep, so only one half of the brain sleeps at a time.

One drawback is that I hit a wall if I stay up for more than about five hours without a twenty to thirty minute nap. My concentration and energy seem to vanish in a matter of minutes and I absolutely have to go take a nap. This can create some problems in social situations, but one can somewhat shuffle the naps around to adjust for this.
Another drawback is that my appetite is substantially larger and I will often crave strange things that I don’t recall craving in the past. One great example of this is grape juice; I now drink this regularly, but before I switched I don’t recall ever wanting it. My speculation is that my body isn’t producing enough of some chemical that it would normally produce in stages 3 and 4 deep sleep.
Other Effects
One particularly noteworthy effect (I consider it a benefit, but others might consider it a drawback) is that all of my dreams are very intense and I find myself remembering them as well, down to minute details. Personally, I don’t have any difficulties handling the imagery that my dreams produce, but many people have difficulties with their dreams in a normal sleep schedule - if that is the case, Uberman is simply not for you.
Conclusion
Uberman’s sleep schedule is a potentially dangerous way to increase your waking hours. Although I found success with it to this point, there still may be physical and psychological dangers that I have not yet met, and there may be grave difficulties for others attempting the cycle.

That’s interesting. From what I have read about melatonin, it sounds like his brain is ramping up production. Has anyone shown that DMT is produced in the brain yet? Maybe you just need to find the right sleep schedule.
^^I’m pretty sure endogenous DMT has been backed up by multiple white papers as of the last edition of Strassman’s book, but I’ll check up on that assumption today.
All this about sleep is really interesting. The real question is whats so essential about sleep that small animals can die from being kept awake to long. Anyway could you suggest any particular books by Strassman, or anyone even, that explain the production of DMT in humans.
GM: Do you believe in the legends that mystics could stay awake for years at a time?
TW: Possibly the fully functional neo-cortex may have evolved to a point where it could recharge as it operates. A few lucky people who are born with such left [hemisphere] damage that it just cannot dominate would have easier access to the enhanced abilities/experience of the right hemisphere and whatever its real sleep requirement is.
....
GM: Gardner said exercise was the best thing to keep him awake. What did you do to keep yourself busy?
TW: Staying hydrated is important. During that initial period you are irritable, straining the part of your brain that’s normally in charge. People get dysfunctional—I accept that. It’s about getting through. Any activity you can do is great—listening to music, dancing, going for walks. Things that are rational like reading are OK for about 24 hours, but then they seem to take you to the most tired part of your brain. The key is just not sitting down and getting too comfortable. You come out the other side and end up less tired.
And from the intro:
Wright, 43, readily admits his feat was a PR stunt designed to drive interest in his radical theory about diet and brain development (and perhaps sell a few copies of his self-published book Left in the Dark). He claims that as humans have switched from our ancestral diet of fruits, vegetables and nuts, to our current meat- and fat-laden culture, we’ve lost access to important hormones that protect the left side of the brain during its development. As a result, Wright says, not only does the weak left-side of the modern human brain get tired out more quickly than it should, but the connection between the hemispheres is also damaged, meaning that we’re not able to tap into our fully-charged right hemisphere when we get sleepy. Wright claims, by changing his diet and using meditative techniques, he is now able to switch over from his tired left hemisphere to his right, which he says can go several days without needing a recharge.
Intentionally stay awake?
These men are beyond madness.
If I stay awake more than 3 days, it gets easier, but it certainly doesn’t help me to sit around and do nothing for even more of the day.
Sheesh.
I think I have spent a lot of my time awake trying to go to sleep and the only thing that seems to work is Art History lectures!
Anyway, my most insane bout of Insomnia went 5.5 days long, but that was only on 2 hours of sleep, after being awake for 3 days on 2 hours of sleep, compound that a couple more times and you’ll get my total sleep for 14 days at about only 8 hours. Yeah.. it was a riot of a time.. sort of. On the second to last day I drove my car 300+ miles up in to the mountains and hiked for a few hours, stayed the night, then on the last day I drove my car 300+ miles back to my house, slept for 2 hours, then woke up and drove 400+ miles back to my parents house. I did all of this completely sober of all drugs/stimulants as I am a strait edge individual.
I suppose my new found spiritual connectivity has allowed me to be more able to sleep, though.
I think this PR stunt guy you speak of is seriously wasting his time by avoiding sleep… sleep can provide you with the most profound experiences!
I read a couple theories about people sleeping the way dolphins do with one hemisphere of the brain being active by doing different activities to let the other parts of your brain rest. So they could basically live without sleep if done properly, not that it’d be too healthy. If i find the article with more info on this i will post the link.
Since the mid-1960s, the rate of obesity in the United States has nearly tripled to one in three adults. Over the same period, U.S. citizens have deducted, on average, about 2 hours from their nightly slumber. Is there a connection?
Endocrinologist Eve Van Cauter strongly suspects that there is. She points to seven studies that have linked body weight to how long people sleep.
In her lab at the University of Chicago, Van Cauter has also been showing that blood concentrations of hunger and satiety hormones—as well as food preferences—depend on how well-rested people are. For instance, in the November 2004 JCE&M;, her research team reported that prebreakfast concentrations of the satiety hormone leptin were roughly 20 percent lower in 11 healthy men who had slept only 4 hours a night for nearly a week than when they had slept 9 hours nightly.
In the December 2004 Annals of Internal Medicine, the researchers reported similar leptin differences in 12 healthy men after just 2 nights of each sleep regimen. Moreover, daytime concentrations of ghrelin climbed 28 percent during the sleep-deprived cycle.
After the second night of sleep deprivation, the recruits’ appetites and food intake increased by 24 percent, compared with those after a good night’s sleep. Moreover, when sleep deprived, the volunteers chose to consume a larger proportion of their food as high-calorie, carbohydrate-rich items, such as crackers and sweets. Those foods represented 33 to 45 percent more of the caloric intake than they did when the participants were well rested.
Van Cauter has also found that sleep loss increases the activity of the vagus nerve, the trunk line for signals between the gut and the brain. During stress, the brain signals the gut to alter its release of appetite-controlling hormones, which might be the mechanism by which sleep loss changes eating behavior.
People are the only animals to voluntarily ignore their sleep needs, according to Van Cauter. They stay up to play, work, socialize, or watch television. However, she adds, “We’re overstepping the boundaries of our biology because we are not wired for sleep deprivation.”
Say you’re taking piano lessons and you learn how to play a scale. The next day, you’ll find that “sleep has enhanced the information that you learned, so you’re 20-40% better in performing those motor skills than you were the day before,” Walker says. “Your brain has continued to learn in the absence of any further practice, which is quite magical.”
The window of time for that improvement is limited, however. If you’re a college student and you pull an all-nighter after the piano lesson, you lose out on the memory enhancement permanently, even if you sleep the next night, Walker says. “It’s not practice that makes perfect,” he says, “but it’s practice with a night of sleep that seems to make perfect. If you don’t snooze, you lose.”
Sleep apparently rearranges memory within the brain. “We presume that it’s organized into a more efficient storage location,” Walker says. “That means you can recollect that information the next day much better than the day before.”
Sleep has this effect only on procedural memories, that is, memories associated with a physical procedure such as playing a piano or riding a bike. These memories are normally used without conscious effort for motor skills that can’t readily be described in words. Furthermore, it’s only light dreamless sleep that works this magic.
By contrast, deep dreamless sleep consolidates, or crystallizes into long-term memories, newly formed declarative or episodic memories, such as what you had for dinner yesterday or the fact that Paris is the capital of France. Sleep stabilizes these memories and prevents them from decaying over time. Unlike procedural memory, Walker says, declarative memory “very rarely improves.” Walker recently found that sufficient sleep prior to learning is also necessary for effectively retaining episodic memory (Nat. Neurosci. 2007, 10, 385).
The brain is steeped in a neurochemical cocktail that changes during the different stages of sleep, Walker notes. The neurotransmitter glutamate revs up the brain, causing neural transmission, whereas the neurotransmitter γ-aminobutyric acid suppresses neural activity. The impact of these two chemicals is fine-tuned by neuromodulators including acetylcholine, serotonin, and noradrenaline (also known as norepinephrine).
“When we’re awake, these three neuromodulators are all swilling around the brain in fairly high concentrations,” Walker says. “But as we start to fall asleep, they start to decrease in concentration.” Acetylcholine drops to its lowest levels during dreamless sleep. During the transition to dreaming sleep, noradrenaline and serotonin levels remain low, but the acetylcholine level begins to rise, reaching twice the waking level in some parts of the brain. The body cycles several times between dreaming and nondreaming sleep throughout the night.
The three neuromodulators are probably intricately involved in the impact of sleep on memory, Walker notes, though for now, that’s just an educated guess. “People know a lot about the brain chemistry of sleep, and people know a lot about the brain chemistry of memory,” he says. “But very few people have started to try and put those two fields together to understand why sleep seems to offer these benefits to memory. We’re really just starting to scratch the surface now.”
In a 2005 study published in Sleep, Nielsen showed that losing 30 minutes of REM one night can lead to a 35 percent REM increase the next night—subjects jumped from 74 minutes of REM to a rebound of 100 minutes.
Nielsen also found that dream intensity increased with REM deprivation. Subjects who were only getting about 25 minutes of REM sleep rated the quality of their dreams between nine and eight on a nine-point scale (one being dull, nine being dynamite).

Yes, this has been my experience.. but then I wake up feeling absolutely hammered tired!
What’s the point of sleep if you can’t function well in the world the next time you wake up?
Hrmm…
I love my multi-verses but I would rather get enough sleep to function like a “normal” than an absolute psychotic person (I am surprised I am still walking the streets some times.. what with the insane things I say some times on lack of sleep.)
Still.. I suppose if you didn’t have a jorb or had a free week to vacation… a good old DMT extension in your REM sleep phase would be dynamite!
(by my experience, it actually is quite amazing.. but it can confuse you when you wake up and can’t remember who you are for about 10 seconds)
I remember coming across this awhile back. Too bad we’re virtually caught in a web of 60hz just about everywhere we go! No wonder people have so many sleep problems these days.
