Yep, sleep deprivation is a killer! It is widely published that it causes temporary psychosis. Combining it with stress and over mental exhaustion PLUS psychedelics? I have no doubt you would have something like that.

Our brains aren't made of iron, we are very soft and delicate beings and things affect us greatly even if we aren't aware that they do.

If you keep having problems then go the doc and get a prescription for some atypical anti-psychs and it might help even you out and send you to sleep next time it happens. Benzos would have been your friend in that situation to. It is frightening, I know because I have been there.
