I don't usually hear things.
I just see them.
Fast moving black things from the corner of my eye.
Everything gets yellowy.
And everything seems to be slightly to the left of where I see them.

My mom says that when I was about 11 years old, I held a conversation with "someone" for about an hour. When she came in to check on me, I told her that the "thing" on my chest thought I needed aspirin.
