I think it is quite normal, for as long as I can remember I used to have spells where if I concentrated on something everything looked really far away, like I was distancing from it, I remember this from when I was as young as 9, I used to tell the doctor about it, IN PASSING mind, never as a primary symptom, if I was there about a chesty cough for example, I would usually ask about it, just out of curiosity, nobody ever had anything to say about it, and I never worried about it at all, it was only SHORT spells.
however this time things are different, because if it was just the odd spell then OK, problem I have is it came, and stayed, so I live in a surreal detached world 24/7, it is so totally 24/7 I almost get used to it, forgot what it feels like to be connected, I pretty much am trying to just ignore it and get on with my life at the moment, its a little frustrating mind, because if truth be know yes I would really love to just wake up one day and see the world normally again.
there seems to be nothing anybody can do about this, nobody seems to care about what I am going through, doctors cant see a cut or a broken bone, so they don't care, friends see me walking and talking so they don't care, they just laugh and call me a hypochondriac, and family is supportive but because I can act normal nobody remembers there is anything wrong with me at all, I just live alone detached form my environment.
