This makes a LOT of sense to me. That's how I explain things, not sure if it's dreaming or real. Sometimes I have to check things or with ppl to see which one it is. I have a very hard time staying focused, especially in therapy. I lose my train of thought in mid-sentence, I can't imagine what ppl think. (Well, ok, I CAN imagine, and I don't like it)
I just talked with my t about trying to stay present in my body in therapy. I zone out and don't really know what she is saying. She said she will at times in session ask my how far away from my body I am, and bring me back if necessary. I hope this helps as I have been getting nothing done in t.
As I read your post my eyes got bigger and bigger because it sounded so much like me. It is so hard to explain to others, isn't it?

Take care! HUGS!
