My bed is shaking and moving gently by itself at night. my cat starts chasing an enemy that is invisible to me. sometimes other things in the room move. at first i thought i had a room that just got quickly infested with a microscopic bug. like bed bugs or mites. and there were so many that they traveled in groups and were simply very powerful! i was disgusted but i was determined to get them out! now i am watching the cat as she spends hours in fear and chasing something small and invisible to me ! and can't sleep every night because the bed shakes as if there is a living being stuck in the mattress! i have never had an experience even close to this...what in the f*** is going on???????
