I am having a strange feeling in the back of my head. The first time it happened i was sleeping and it woke me up and felt a rush to my body and everthing around was moving at 100 mph. It felt like someone was pushing me from the base of the back of my head. Its been three days now and hasn't been as bad. But it is a content feeling of goose bumps on the back of my head. And now i can't sleep everytime i try to sleep i get a falling feel or a feel like someone is pushing my head forward. ???? Please help
