Periodicall, I sense that I am back living at some earlier point in my life. The feeling is very real although I remain fully aware of my present place, time etc. It is somewhat similar to what one experiences waking up from a dream yet the feeling state is that I am now back at an earlier time.

If this "shift" places me as a child just finished riding my bicycle sometime in the past, then I feel I could ssimply walk over to my friend's and play a game. It is important to note that this is far more "experiential" than simply remembering; I actually feel the change in time and place.

I have been struggling with all the usual demons of depression for over 30 years. When I experience one of these "time shifts", I feel like I've come out of a bad dream, that being depression and I feel like a new person.

Because of the way this experience presents, I am curious to know if this is some form of dissociative disorder.
