I'll sometimes have flashes where if I move my head or stand up quickly where I go completely insane. Literally. For about 2-3 seconds (which seems like an hour) I'll just completely lose touch with reality. I usually think I'm in outerspace except all the stars are within my reach and are really tiny, like they're just a bunch of fireflys. I'll also get wierd out of body experiences where I'll see myself and I kind of look like a cartoon character. That's only if Im on shrooms and weed though. But it's never unpleasant.
