as a child you created an imaginary friend, you talked to him, played with him as if he were real, and all your memories of him seemed real. But when you grew up, you simply forgot about it, thinking that it was just a child's imagination. A little later, you were looking through your childhood photos in an album, you found an unfamiliar guy in the photo, he seems very familiar to you.
You remembered how you played with him as a child and he gave you something, it was a bracelet. You rummaged through the nightstand and found it. How was that possible? Murphy was an imaginary friend, right? While you were trying to figure this out, he, Murphy, was watching you from the mirror behind you. It seemed he was stuck in the mirror and couldn't get out.
