(Time and Mind)

Shifting does distort my sense of time.

Perhaps though, you might also look at it as having your memory affected as well. If your experiences from 4:00 to 6:00 are blocked out, then it will seem like that time did not exist. When you experience things in great detail, and retain the memories, it will seem like time slows down.

As for blocking out memories... it's what people in Psych-land call "losing time". Although I've brought this up a gazillion times, I'll mention it again... Do some reading about dissociative disorders. The differences between what people here call "wereism" and what the shrinks call "dissociative identity disorder" are very few. (Yes, including p-shifts.)
