I've been getting this a lot lately. Is it normal? It seems like it happens to me the most after a long day in the office when I'm sitting in traffic and my mind has just completely shut off. I'll be looking at an area I've known for like my entire life and it will look as though I've seen it for the first time in my life. I find it to be sort of unpleasant but at the same time I find myself completely bemused by it, almost like I'm in a trance. Has anyone else experienced this?
