Horrors of Bob: Part I

-Bob loses something, and it is returned to him by a stranger. The person seems nice. However, he starts getting calls from the stranger at all hours and yet Bob never told them his name, nor does the object they returned have any indication about his identity (it something like money or a set of ordinary pens, something he was surprised to be returned, due to the items value or lack thereof).

-Bob is asleep in his bed, and he wakes up to the sound of drops falling on water. He looks around and the bedroom floor has turned into a black ocean in which he can see things moving underneath the surface...black, tentacled things (and they're not octopi).

-When walking down a hallway (mansion, hotel, whatever) Bob suddenly notices a set of bloody footprints being imprinted on the carpet, passing from one wall to the other, as if an invisible person just walked through one wall and continued across the hallway through the other wall.
