Once in a while I will have an orgasm in my sleep that is so intense it wakes me up. It will always be during a dream but the dreams are never sexual in any way, something random will be happening and then I'll start having an orgasm in my dream but then it wakes me up bc it's a real one. Also the orgasm will be really intense, more so even when I have one during sex or masturbation. It's really weird. I had them more often when I was with my ex boyfriend, and we were frequently sexually active. After we broke up and I wasn't having sex, I still had a few but farther apart. Didn't notice any pattern at all. Really strange but I'm not complaining haha.
