I know what dissociation is and due to my traumatic background, I do experience it.
As I read your post, I cannot help but think you are describing something more like "highway hypnosis," which is something we all tend to experience as we drive down the road. We go on auto-pilot and do not always remember every mile we have driven.
Are you familiar with "highway hypnosis?"
Is this akin to what you are experiencing?
Even if you are dissociating, it's not very likely you will remain dissociated forever.
Yes, please do run your experiences by your pdoc and your T.
