Vampire
Where is this man’s reflection in the mirror? This girl does not know what she is getting into and she better make a run for the door before he bites her on the neck. Isn’t it obvious that she is sitting next to a vampire? Get out of there quickly, he looks hungry.
We do not really know how this illusion was made in the first place, we can barely see him at all in the mirror reflection so we are going to blame it on the angle of the photo. If you look carefully his arm is visible, so it’s just a funny mistake.
