If you own a cat, then you might be familiar with this phenomenon. This happens with such frequency, that I ascribe to some sort of random body sensation, like a phantom phone buzz.  You try to ignore the distinct pressure of a cat jumping onto and then walking on your bed. It generally doesn’t abate until you reach out into the blackness to confirm that there’s nothing there.  The shit of it is 1 out of every 10 or so times it winds up being your actual cat.  Anyway, it bugs the hell out of me.
