Thank you for replying.
In answer to your questions, I can see and remember everything that is happening, but cannot directly effect any changes. I do not seem able to turn it "on" or "off" so to speak.
As I can see and (vaguely) remember what happens, there is little obvious disorientation, except in terms of time. That is to say, I feel disoriented, but have learned to hide it well. As it happens often with people around and I do not like to make a big deal about it, I generally don't.
I do not know how long I have been out of sorts, except on those odd occations when I am watching TV and can count commercials or estimate in some other way.
With that said, I have not asked anyone whether my recollections are correct. They feel right, but them they probably would anyway.
