Found something

I found a small pearl like thingy in my bed. Maybe it's fried up fairy dust atau something? It looked natural and it was small. It wasn't there when I fell asleep and also it was near my head just below my pillow. I've never seen it before in my life and I don't have jewellery with that atau any crafting sets with it. I have no idea what it is. Any thoughts?

Kind regards.
