My occurrence happened a few years ago. I was just about to go sleep when all of a sudden out of nowhere I felt this most tranquil state of mind, wishing for world peace and goodness for all mankind.
After that things started to get a little weird, I fell asleep with the lights on. I felt heaviness on my legs. I woke up to see what it was, maybe a pillow on my legs or something. I saw that there was nothing there and I went back to sleep. Then I felt something separating my legs apart and someone in between them. So I changed my position and started to sleep on my stomach, something I never do, and then I felt some heaviness on my buttocks. I felt someone lifting me into different positions all night and I kept waking up in between them but never fully believing if it was really happening or not... But needless to say the next morning I woke up I was sore. I thought I dreamt all of it but when I went to go take a shower I had bruises on my waist that weren't there the other day.
I don't know if this means anything but the day after was Valentine's Day... I don't think it's an incubus because I wasn't paralyzed and I felt peaceful before the whole thing happened but I don't know what it was... If someone could help me with this, that would be great!
