There is a period during sleep where the body engages in rapidly flushing the brain of cerebrospinal fluids. This action is intensely physical and disturbing, however with the exception of the most serene true-insomniacs only a tiny fraction of people will directly experience it.
They say this prevents the build up of harmful toxins in the brain, and that the failure to do this over time can be a contributor to the onset of conditions like Alzheimers.
While many may claim to have overcome the need for sleep, and some actually feel productive. And claim to be just as effective. No one should be in doubt that long term effects of sleep deprivation is devastating. Not only to the Brain, and the body as many studies have shown.

- e40 7y agoThis action is intensely physical and disturbing Can you expand on that?
- dagaci 7y agoIf you are very relaxed, but persistently unable sleep. But are not alarmed about not being able to sleep anymore, and in a state of almost like not thinking. You may suddenly experience a throbbing sensation in the head/neck, a pulsing in this state. Normally this enough to trigger alarm in the conscious and fully wake you up. But after this happens many times you can become expectant of it and just let it happen a little longer because you are not immediately alarmed.
- michannne 7y agoIs this the sinking, tremor feeling you get after your awake state, but before the sleep state? That weird limbo where, if your brain jolts back on from this state, it's as if you awoke from a dream - even though you only dozed off for a couple of seconds?
- jlokier 7y agoI have experienced something that sounds like this, but during the first few minutes of falling asleep after a long time without. Sometimes I woried that I was going to "pop a vessel", but after a couple of times, didn't worry so much. Is it the same thing as you mean? I never experienced it "spontaneously", only while settling down to sleep before drifting off.
