Got That Spacey Feeling?

I came upon a couple of interesting articles lately that explained that "spacey" disconnected feeling I always used to get after I logged off after playing for several hours. I always thought it was just me... The first is an article about people who absentmindedly execute certain "moves" from their games in real life, starting with a woman who tries to "pick up" things as you would in Katamari Damacy. The other is an account of a panel discussion hosted by the International Game Developers Association (IGDA) about video game addiction which talks a bit about disassociation, i.e, that "spacey" feeling.
