To answer your question, yes, I've felt like that for the last two years. I think there's something wrong with my brain.
kikimm - That was a very good description. I feel like that sometimes too. It even happens randomly when I'm talking. Sometimes I'll be saying something and then my mind will just zone out but I'll keep talking without even thinking, kind of like auto-pilot. Scary. Happens a lot when I'm driving too, I'll just lose touch with reality. What really frightens me is that drugs seem to be the proper adjustment for whatever is wrong, which is truly scary to me.
