I really feel for you, I have those often-mine are often insect related. I'm OCD and in the middle of the night I will jump up, throw all of my covers off my bed and search for any kind of bugs. I always panic that my room is infested even though I'm a complete neat freak and haven't ever had a problem, i once even spent the night spraying down my room. I have other panic attacks at night some times not relating to anything, some about other fixations but i know how you feel and its awful. Well-i wish you the best!!
