Water coolers go glump-glump in the middle of the night. Squirrels, raccoons and cats invade our basements and attics making weird, unearthly noises. Birds repetitively knock walnuts, almonds and dates against our roofs in order to break them open. Power surges make our radios, televisions, VCRs, and computers act as if they are possessed. Dogs howl at the moon and sing with ambulances and cats freeze in their tracks.
Light bulbs go out and overhead lighting reflects on our glasses as eerie vortexes and orbs.
A household member gets up in the middle of the night, stumbles down the hall and rummages around in the dark in order to find himself or herself a snack. There are certain times when you can make the safe, if terrifying, assumption that someone or something is haunting your house. Inanimate objects begin to take on a life of their own. Lamps, television sets, radios, and computers turn on and off without the intervention of a living human or a remote control. Windows open and close without help.
