I'm sorry that you've had to go through that. My experience is similar but more benign. I too lose time but during that time I have never done anything but sit and stare. I guess I should have been more clear about what I meant by dissociation. My dissociation preference is when I become a completely numb zombie on auto pilot. I don't have any emotions, hardly have any noticeable thoughts or opinions and, best of all, no flashbacks or memories. It's like numbing a bad toothache. Just a couple of hours where I don't feel like a raw nerve on the verge of a breakdown.
