Well, this type of stuff is really hard to define in my opinion. I can only compare to what I experience so I suppose it could be different for everyone. I don't like worrying too much about terminology for that reason. Perhaps you were in some stage similar to SP. I do have dreams from time to time where I am sluggish and it is difficult to move. It makes me wonder what that is. Perhaps there is a part of me that's slightly lucid and it confuses my subC.
