I just saw this thread for the first time and thought, "LD got a lot of hits." I know it should have been "posts," but I guess my brain makes typos too ;) The reason I thought it was a new thread is 1) I'd never seen it, 2) The first and last post were in July, and 3) I'm dumb like that. Anyway, I thought it was such a great thread that I started reading the whole thing from the beginning and suddenly found myself thinking, "MEGABYTE POSTED!" That's when I realized my folly.
After playing guitar on Guitar Hero or Rock Band for a while I can't play a real guitar for crap, but this isn't really bleedthrough since no one can tell the difference :p
I've had bleedthrough like moments before, but I realize what I'm thinking so that probably doesn't count. On the other hand, I've often had a sort of haze or disconnection after playing for a long time or watching a movie in a theater. Once in college after watching a movie with my wife I treated a red light like a stop sign without realizing it until the blue lights from the cop that was right behind me woke me from my trance. That was scary. That cop had to actually wait for traffic before going through the intersection. I'm surprised he didn't give me a ticket.
