Love this, @rakushasu. Oh my gosh, I got the creeps from the very beginning. And I have to tell you the funny thing that happened while I was reading it.

When I came to the following lines...

My attention was drawn to a weird little object behind me. Resting on the bathroom floor behind me was a small black cube. What the hell, I wondered, as I brought my face closer to the mirror. Why’s there a-?

... just then my cat let out a really creepy yowl right near me and I jumped out of my chair! So I guess I was pretty involved in the story.
