When dd1 was a baby I lived in a caravan outside of a derelict cottage in the middle of nowhere. As soon as I first set foot inside the place I cried..I could feel that there were the spirits of children there and I felt overwhelmed by a feeling of sadness.
I bought a wooden puzzle for dd at a car boot sale. It was one of those ones with pegs to lift the pieces out, and when the pieces were put back in they'd make the sound of the respective farm animal. The donkey noise didn't work, but the others were fine.
Dd's toy basket was at the far end of the caravan from my bedroom, and every night as I turned all the lights off and got into bed, and the caravan was in total darkness, you could guarantee that within a few seconds the puzzle would do one of its noises, every time without fail. Never happened any other time of day.
This carried on for many weeks, and one night I had some friends over and I was telling them about it. They thought I was nuts for still having the thing in my home, so I picked it up to hurl it into the garden. As I did so, it went crazy and started doing all the noises, all at the same time. My heart was going like the clappers, and I was glad to be rid of it. It landed in the overgrown scrap heap of a garden, underneath the bathroom window.
I didn't have running water in the caravan, so I had to take baths in the cottage. It was really creepy and manky in there, and I would go in while dd was asleep, taking the baby monitor with me. Many weeks after I had slung the puzzle out, I was lying in the bath when it popped into my head. I thought about how bad it would be if the puzzle still did it's noises, and I shit you not, within a few seconds of having that thought, a faint 'baaaaaa' came from out in the garden. After that, this happened regularly when I was in the bath, but ONLY if I thought about it. Sometimes I'd genuinely manage to keep it out if my mind, but every time the bastard thing popped into my head, like clockwork a few seconds later I'd hear it making one of its noises from outside. Never , ever heard it any other time.
Was glad to leave there, after more than a year.
