My mother's dog does this.
When housesitting for her while she vacations, I usually sleep in the basement. The dog sleeps up on a dog bed on the ground floor living room. No matter the hour of the day or night, no matter how quietly I tip-toe, how slowly I turn doorknobs, or how gently and silently I sit down, within moments of being fully seated, he jumps up, dashes through the house, down the stairs and comes to stare at me through the open bathroom door (if closed, he paws at it, which is even more annoying). I don't know how the hell he does it; I am NINJA-SILENT! Damn dog has some sort of psychic toilet-sense! O.o
