I’ve told this story before.

I cannot fall asleep on my back. Or rather, I find it incredibly difficult to do so.

One night, I was dead tired and laid on my back as I normally do to get the bed warm before turning on a side to try to sleep, and I began to drift off.

It was at that point I became aware of the dark shapeless form about as tall as a person stood at the side of my bed. The room was dark. It was darker.

I made a very weird “oo-er” noise, roused myself and it melted into the regular darkness.

I didn’t feel at all threatened by it, and assume it was my mind playing tricks, but it was definitely creepy and unwelcome.
