Whew! Finally something abnormal that is normal! HA!

Not that I'd wish this on anyone.

It's ALWAYS spiders I see. But I've felt the bed move before while falling asleep and have heard people walking or music at night. I guess these are part of it too.

It does seem to happen during times of stress. Perhaps it's related? Either way, thanks for the replies! I didn't know such a thing existed let alone that many people experienced them too!
