When I get really engrossed in something, I become hyper-self concious upon returning to the real world.
Its not a bad or unpleasent thing. The other day I was watching a movie that featured a vampire who was quite graceful and beautiful.
When I... woke up, I guess, I was extreamly concious of my movments, and was aware of myself feeling surreal and vaguly graceful.
As I was reading The Fountainhead, I would occasionally pause to mull over a sentence. During those pauses, I was extreamly aware of myself, of my shirt touching my skin, or the soles of my feet.
