Question: Right in front of the Uvula ( flap that hangs down from inside of mouth by the back of the tongue.) There is a hole that goes up into your head. If you put your thumb in there you can feel it. When I drink liquid now, I can feel whatevers in the center of the top of my head ( Brain ?) move up and then down. What is in the center of your head right underneathe the top scalp? The brain? Im seriously sitting here in a stable frame of mind telling you that it moves up and down and other ways by itself. It almost reminds me of a thick post. The only things t hat logically make sense is the brain, or a worm of some kind. i TRY TO SWALLOW and feel the top of my head move as if terrible pressure is being put on it. SAME thing happens when I raise my eyebrows/ I am wondering if somehow you can slip up that far and not know it. Ever heard of t his?
