Hmm, I've never really confused my life with in-game life before, but I wonder if I maybe do it on the subconscious level. An interesting note: when I tried playing Morrowind (for those who don't know, that game has a huge open world with many huge areas that are there for no reason other than to add realism), I had a sort of paralysis, because I had to explore every room and open every door, but that's simply impossible in that game.
