It happened again

It happened again last night. I had another night terror where I'm convinced that something in the bedroom is firing darts at me. And in order to avoid said darts, I leapt out of bed with the skill and grace of a ninja and landed on the floor. On the other side of the room. You know, where the darts couldn't reach me. Apparently what actually happened (again) is that I flung all the covers onto my unsuspecting husband and hurled myself into the air, landing (somehow) on the floor by his side of the bed, bruising my knees/shins/elbows in the process. Is there a scientist out there willing to find a natural cure for night terrors? Anyone? Anyone?
