True story,
Once on a Saturday I took the car to get a tune up. We had just gotten married and were renting a cabin in the woods on a nice old ladies estate overlooking the Potomac River.
10 minutes after getting to the tuneup place, my wife calls. Turns our she had been on the bed, which was then just a couple of futon mattresses on the floor, with the pillows propped up against the baseboard heating which ran along the wall. We had just adopted two cats, a semi-feral mother and kitten who were just beginning to realize we were not bad guys and would tentaively come onto the bed with us if we didn't make any quick movements.
So my wife is sitting in bed reading and trying to coax the cats to join her, but they both sat at end of the bed giving her strange looks. She got tired of this and decided to do some cleaning and was vacuuming around the bed and when she picked up a pillow and found...an six foot black snake curled up inches from where her head had been a minutes before.
So after she climbed down from the ceiling she gathered up the kitties and fled into the next room and called me.
Of course the car had already had all the ignition wires pulled, but I got a ride from a snake-phobic mechanic back to out place and promptly deposited said snake back out into the garden.
