Question: I’ve had these sleep paralysis episodes more than a few times. You can’t seem to move even after trying to force yourself. Once it felt as if something or someone shook me awake. This caused me to have a heart attack I thought at the time but when I was examined at the hospital the doctors thought it was an anxiety attack, but later on in life test has shown that I’ve had a myocardial infraction (heart attack), what’s the deal with my head.
