Ghost in my apartment

Oh, heck. That had to be an Aether ghost, right? I knew that weird crystal ball must have been an Aether thing.

I’d never seen anything supernatural before. The ghost was dusty, transparent black, as if made of soot, and taller than a normal person. It was also very thin, but not skeletal, more like a stick figure come to life.
It was sliding its weird ghost hands along my bed and wall in slow, drunken, groping movements. Eugh. It made me shudder just to look at.

What was it looking for?
