I have episodes anywhere from 5-15 times a month, it typically occurs a couple times in one day if I have one that day. Some episodes are different than others; some I can relax through, and with others I hallucinate, have out of body experiences, and the worst episodes are the ones where I have to fight for every breath. I've had this since I was young and it has gotten progressively worse with age. I am currently 22 and I lose a lot of sleep over the fear of an episode. I feel like it has gotten out of hand.
