My girlfriend talks in her sleep

Occasionally my girlfriend talks in her sleep. Once I woke up to her saying "what's that?"

Me: what's what?

Her: what's that!

Me: what's what?!

Her: what's that? In the corner!

I don't think I have ever turned on my phones flashlight faster.

After seeing for myself that there was nothing there, and trying to explain it to her, she promptly flipped face first back onto her pillow.
