An odd thought I used to have when I was younger was wondering if someone else was somehow looking through my eyes. I would try to not hear, think or feel anything and imagine what the other person would be experiencing. It gave me an odd, very slightly disorienting feeling.

I remember that feeling, and have been getting it a lot in the last few years. I believe it may be depersonalization. I am significantly mentally ill and socially isolated. I am nocturnal, I live alone, work alone and have no friends and limited contact with family. I spend nearly all of my time day dreaming. While I am doing that, I imagine myself to be what is essentially a different person that is just loosely based on me. I sometimes find myself forgetting that I, the person typing this, am even real. It's not that I actively believe that I am not real, I just forget that I am. The few times I do have thoughts of my actual self I find it quite distressing.
