I can relate to the experience. I've often had false awakenings where I'm apparently lucid, though when I get up and attempt to clothe myself, I'm haltered by some strange force that leaves me stuck in a certain position. It's as if my mind is lagging behind, and everything around me, even the make believe sounds of my folks preparing to leave the house and go to work, are all sluggish and twisted. It's rather weird and unpleasant.
