I am 46 , and have done this since I was a teenager! At least that's as far back as I can remember ! It can be a noise that startles me out of my sleep, or my husband can roll over in bed, or nothing at all wakes me up, and I sit up in bed and scream! My husband is good about it, but I feel bad he doesn't get a good night sleep, and niether do I! The other night was a bad one! I must of screamed quite a few times. After it was over, I had no memory of any dream or nightmare. I usually don't! My heart was pounding fast for a few minutes after. The next mornig I had a bad sore throat that lasted a day or two!

Anybody suffer this same thing, or know what is causing it?

I don't remember anything tramatic in my past!
