I think you mean a sleep disorder where you "can't" tell the difference between awake and asleep?

In many posts, you have mentioned the thoughts that you find troubling for their content. Perhaps these thoughts-- which is all they are-- fit into that category. They are just thoughts, which, like feelings, are just present in our internal world, sometimes they have important meaning, sometimes they don't. sometimes they give us clues or other information, sometimes they just don't. When I worked at a place where I was unhappy, I used to have thoughts about setting people's office doors on fire. The thoughts weren't particularly homicidal and I've not hurt any living creature deliberately and I didn't "want" to do it (and didn't!) in the non-fantasy sense. Yeah, I was a little pissed off, some of it legitimately for mis treatment and some of it more for ego bruising and/or past betrayals. I don't know too many people who haven't had thoughts and feelings that are not in line with what they might actually do or even how they really (constructively) feel and respond to the world.

But whether they are "just" thoughts or might be something important that's going on with you, never a problem to discuss with your T to try to figure this out. So the standard advice on this board would be to bring it up, see where it goes.
