I'm not 100% sure but if I took a shot in the dark I'd say I would personally identify that as being some form of dissassociation because that's round about how I would describe myself when I dissassociate. Others may give different responses. I'm not sure that I've answered what you asked simply because you've already stated that you have dissociative tendencies and have not alikened your personal experience of the description in your 3rd paragraph to being that. Hope that makes sense. Hopefully you will get some clarity soon.
