I am an active sleeper

so to tell this story, I have to set the scene.

when I go to bed, I have a light soft fleece blanket and on top of that a weighted blanket.

So got that image: me, soft fleece, heavy weight.

So this morning, I woke up to discover I had somehow switched the two blankets, and now the weighted one was under the fleece one.

I have no idea how I did this . . .
