Something that has always been at the back of mind and kept me wondering is if a sort of controlled hallucination, like a lucid dream in the day, is possible. Would it not be awesome to, while in a boring class, create some kind of mini-war scene on your desk, to throw fireballs around the room?

I've never tried to train myself to do this, mostly because I am scared of the risk of losing control of the hallucinations, and then having episodes like in the movie "A Beautiful Mind", where the hallucinations don't go away (or in his case, he just got mentally ill... I think it was schizophrenia).

But anyways, has anyone ever tried this, and if so, what was the success.

Also, Has anyone been able to control the imagery in your head? Its very hard to be able to control imagined images, and even when I was little i remember it was difficult to keep an image in my head without it morphing into something I didn't want or moving away etc.

Has anyone ever experienced a "3D" sensation when you close your eyes? It's happened to me once, when I was meditating, and all of a sudden the blackness seemed to become three dimensional and it felt like I could move through it like the ocean, but it ended.

BTW, here's a link on Controlled Hallucinations: http://www.bio.net/bionet/mm/neur-sc...ne/024159.html
