Bless me

Early this morning I was woken by sudden and violent sound. I lay in the dark with my eyes wide open, and had the bewildering and incoherent impression that my face had just exploded.

My face was still there, however (although a little damp), so I played back the sound in my head, and eventually came to the conclusion that I had sneezed in my sleep.

I didn't even know that that was possible, although I suppose there is no reason why it wouldn't be. It just seems odd. I certainly don't remember it ever happening before, even when I've had a cold.

Actually, would I even know if I had done it before? Would it always necessarily wake me up?

Have you ever sneezed in your sleep, that you know of?
