Replying to Long term acid side effects

My math teacher has prob the shakyest hands in history. he cant even seperate a piece of paper from a stack. hes always telling us stories about talking to bears or how he slept outside under a tree and woke up to hundreds of spiders falling down on him. anyway today was our last full class of the year and it was a freefor all. some of us were at his computer listening to his phish collection on windows media player and had the visual up on the tv. it was the spinning tunnel type thing. the dude saw it and stared at it for a good ten minutes. he was turning his head from side to side and staring really intensly.

was this man a heavy acid user or is he just plain crazy?
