Haunted?

My mom has complained a couple of times when she's come to stay with us that our house seems to be just a little bit haunted. It's nothing too alarming, but frequently one of the many electronic toys around our house will start talking or making noises for no reason that you can see. No one is around, no cats bumped it to trigger it, it just starts on its own. It can be a little unnerving when you're alone in a quiet house and this keeps happening.

And I have to admit, it flat out gave me the creeps the other night when I wandered out to the kitchen at 3 in the morning to get a drink... in the silent house where everyone was sleeping (even the cats) I suddenly heard a toy exclaim: "Peek-a-boo! I see you!"

I may or may not have yelped and scurried back to the bedroom to cuddle up to Aaron...
