The prophecy

Indeed I have been attacked by ghosts.
It's mostly just an irritant though.
The ghosts are changing key settings on my computer, making it impossible for me to play Half-Life 2.
The ghosts aren't particularly horrifying. They manifest as small, clumsy transparent people - frequently spilling things. Their "scares" are largely ineffectual and cliched. Owing to poor eye/hand coordination and outlandish costumes these attempts to frighten me seem more like slapstick than anything else. They apologize by explaining that when you're dead it's hard to be on your best game and that without access to coffee many of them feel unmotivated and drowsy until well into the afternoon.

This is a ghost?
