Probably, I should ask, when you are dissociating, Blueberrybook, do you remember what is keeping your thoughts? Is there a problem your subconscious might be trying to solve on its own or is your mind simply entertaining itself? I would be rather scared if I was loosing my thoughts and not remembering what I was thinking about. In that case, I would definitely seek a mental health professional or family member or close friend. More likely, it is probably no big deal.
