Puppets, ventriloquist dolls, all of them are creepy. I used to share a suite with a girl in college who owned a ventriloquist doll. One day I was in the suite by myself, I happened to be looking in a mirror brushing my hair. I could see her doll propped up on her bed behind me. At first, it's eyes shifted left, then it's jaw slowly dropped opened, followed by it tumbling over, and off the bed.
I ran out of the suite, stood in the hall a minute, went outside to sit in the sunshine to gather my wits. Eventually, I went back upstairs and back into the suite half expecting to see the dummy sitting back up on the bed. It was still laying face down on the floor. I scruffed it and threw it in her closet. From that point on she kept him stored in his trunk in her closet because the oils from other people's hands would mar the dummy's complexion. I really think she was afraid I'ld throw the dummy out of the window.
It's amazing what your imagination can do when you least expect it, this was pretty undramatic. I don't suppose this woman ever met Robert, the doll kept in a museum down in Key West. Now that's a story and something worth investigating.
