Thanks for your replies,

I'm not sure that it is dissocative, I feel it is something phsyical. Maybe the inner ear as suggested. I have had trauma but though I tried to forget about it I can't and those memories are vivid (a bit too much, if anything they process themselves every day, playing over and over) and also I truly know the out of body experience which I would be more prone to have and this is nothing like that. I don't know if my breathing or heart rate goes up during this event, I guess I should try to measure it the next time. It feels like it does. Also I can see fine, my vision doesn't change, I can still look at things and tell how far away they are and they don't get bigger or smaller or waver about. I can easily move about and pick up objects, throw them into a trash can or do other things except that movements seem incredibly fast (never slow) accompanied by the "feeling" of space around me is either enclosed or the exact opposite and sometimes both which is weird. I don't know how but it can be both??? I don't know if anyone watching me would see me moving very slowly as I try to slow all my own movements down and not move at all.
