There have been two occasions where I've dreamt that I attempted to move a television off of a table, and it would work. But within the same moment, my body and mind would immediately turn frigid and I'd experience the same type of feelings typical of sleep paralysis. Except it seems more powerful and focused upon the brain. The second dream was more lucid, since I remembered my first experience and decided to try again anyway. Could this simply be sleep paralysis or something else?
