My t thinks my head fog may be derealization, which is moderate dissociation. Dissociation is yet another spectrum; there are a few different disconnects that are considered dissociation. I looked up derealization and it sounds maybe right or maybe not. I do see my surroundings as foggy and surreal but I know that is just how I see them. Some days I probably shouldn't drive because I do feel disconnected, but I still know it is real and react to things. I don't get depersonalization, but one of my kids does. He has to touch things saying they are real, seeing them and feeling them to know this is his experience. That's how he explains it to me, but I don't quite get it.
