The Mirror

After a long afternoon of cleaning your grandmothers attic in the sweltering heat You decide its best to stop for today. You just wanted to go home, take a shower and chill on the couch and watch a movie. But as you turn to walk out of the attic something in the far back corner catches your eye.

"How did I miss this before?" You mutter to yourself as you walk back toward an object covered in a sheet. You notice a small folded piece of yellowing notebook paper pinned to the sheet so you carefully unpin it and unfold it.

The note said:

"Beware the mirror.
For those who look
see things that
no human mind
can comprehend"

"It's a mirror..." You said, "No human mind can comprehend... what does that mean?" You stared at the sheet wondering what you should do.
