What is this and how do I get rid of it.

This may sound insane and hell it is but, I have been having issues with my eye especially my right eye. I thought it was allergies. So I went to the mirror to check my eye. In the mirror I saw a close up of my eye in the reflection ( as expected) but also in the reflection I saw another person IN MY EYE just standing there watching me. I turned and looked nothing. So I looked back in my eye and and I see me, my eye (of course) and the other person. I don't smoke or drink or anything but damn this is making me wanna start. I hear growls, wind (that no one else seems to hear) and things have been thrown and I mean across the room but nothing is there. Anyone else experience craziness like this...how do I get rid of it?
