Yes; I cannot wake up. As if I'm in a hypnogogic state. However, I get some of my most productive work done in this way, sometimes. Outsiders with whom I have encountered have said, when they think I'm not listening, I seem "phantom-like." Not always. There are times I am deeply autistic and far away. I am, however, not vacant. Quite the contrary, I am in deep thought &/or merging. I sense deeply. I see the unseen. But, I am often misinterpreted. I suppose that's the quandry of being an Aspie....sigh. I have a lot of innate discipline and motivation, plus I am very conscientious, which is probably what keeps me grounded.
When I feel "far away" or locked inside my mind, I can become (disoriented?) - not the right word, but close? Oh, I do not, nor have I ever, chemically altered myself with alcohol, drugs, etc. I would never purposely sabotage my enhanced senses. I guess I'm just naturally in this state due to being autistic.
I do have feelings of deja vu, which can be disconcerting. Plus, when I have nightmares, I seem to have a really hard time recooperating. Rough.
