I was kinda wondering what this phenomena is called. I'll be working at my computer or playing a game or concentrating on something and suddenly I don't know where I am, meaning I have no idea which room I'm in, what chair or bed I'm sitting on, what time of day it is, total disorientation. I have to look up and do a reality check. This has been going on for quite a while. It also happens when I'm out about town. I'll be in a store and think I'm in a certain store and I'm planning my route home in my head when I come out of the store, get into my car, leave the parking lot, and realize I'm in a totally different part of town. It comes as a total surprise to me that I'm not where I think I am. This is starting to really bother me and I was wondering if someone can tell me if this has a name and if anyone else has ever experienced it.
