Under the covers, at night.

She likes to hold hands under the covers.

I'll have my hand at my side, and I'll feel her slender, cool fingers slip past my palm, brush against my fingertips briefly before sliding down to lock in with my fingers and then a quick grip of my hand, which I instinctively return, and then she's gone again.

Maybe she just wants to be reminded there's someone else in the dark room. Maybe she heard me snort in my sleep. Maybe she just had a bad dream.

That last one makes me pause...

What do ghosts dream about, and what is a scary dream to them?
