Who's behind you?

So I wash my face at night and everytime I have my eyes closed, I have the scariest feeling that someone might appear behind me when I look into the mirror and possibly hurt me. Someone like this:  

Is it all in my head? Am I just weird? Hmm.. It turns out no, I'm not. There's actually a Facebook page devoted to this fear:

yes, im afraid someone will kill me while im washing my face

Haha! And I thought I was the only one feeling like this!

Solution? 

I wash each side of my face separately to make sure that I keep on the look out if ever somebody appears or creeps behind me. Here's an illustration of how I wash my face: 

The world is a scary place so be wise and wash each side of your face one at a time ;)
