Night time noises

[Bluey2023]

The house is dark, everyone else is definitely asleep and suddenly I hear one of my dds keyboards start playing random keys. It's soo creepy, ahh it's just made another noise.

Cat?

No cat, we do have a dog but not in the same room. Batteries are probably running low, just a creepy in the night xx

DD has a music box that normally plays lovely nursery rhymes which she falls asleep to, when the batteries are running low it turns itself on/off randomly and plays the creepiest version of Old McDonald had a farm, it's like something out of a horror film.
Unfortunately lots of kids toys like to do that when the batteries are low, I was once terrorised by a Teletubby plushie for 3 nights before I figured out what the creepy noise coming through the baby monitor was.

I get woken up to my TV on randomly, I can't sleep with it on so I know I definitely turned it off it happens regularly.

I once woke to my sisters areobic pig toy going off during the night whilst staying over at mums... I about died.
