I'm not sure if what I have is truly derealization or not and but I've read about it and I would like people's opinion.

Sometimes I've been in hotel rooms where nothing feels real and I have this panic that I'm going to swap places with myself in the mirror if I look so I shouldn't wash my hands or look up. It's usually after something stressful. I also have this aura like, I know things are real but are they? I know I'm not going to do anything rash.

Sometimes I say things to people that are really odd because I literally don't care because I don't think what I'm saying will have any impact on the world.

I can't really explain it that well. But it is incredibly frightening when it happens, particularly if I'm in a crowded space which seems to trigger it. The longest it ever lasted was 8 hours and that was very very unpleasant.
