people can and do have psychotic breaks because of this often times because they cant sleep because of taking something like 'dhea' in large enough doses it causes aggression and hyper, unable to sleep, go long enough you'll lose your mind believe your jesus and crap, I had done an experiement in my 20's on this, and saw lights flashing in the sky like a spider web or a graph, that did not go away, I went around asking all sorts of people if they saw anything unusual in the sky, of course the answer was no, and this was as real as anything you can imagine, I often wonder if someone gave me a huge overdose of acid in a drink or something. weird shit always get plenty of sleep.
