Amy clutched her duvet about her feet listening to scratching on the window.

"Enough, you are strong! You can deal with this... whatever 'it' is." She scolded herself into turning on the lights, investigating.

The curtains were drawn, creeping up to them, she reached out and yanked them open...

Nothing.  There was nothing there?

"Must've been my imagination."

Something brushed past her knee, Amy glanced down and froze.  A deep rumble floated up from nothing... from thin air?

Amy reached down feeling... scales?... wings?

A snout nuzzled her hand, leaning into her.  Smoke curled passed her fingers.

"Invisible dragon?... Alien?"
