No, but a few times a year I will wake up with a completely numb and limp arm. That wouldn't be so bad, but since I can't feel it I don't know it is mine, so I feel something foreign laying on my chest and face and wake up with a start. The last time that happened I was sleeping in a basement known for bugs, so I was somewhat on edge about sharing my bed with crawlies. I happened to be sleeping near the edge, was just starting to wake, and felt something weird on top of me. My reptile brain asserted itself I flailed myself clear off the bed.
