What in the world is it?

I was taking a shower last night and washing my hair. (Ever since my family moved to the house the shower creeped me out. It went as far as I pictured someone died in it but got over the feeling 2 years ago.) I turned around and saw some black shadowy blob. Normally, I wouldn't give it a second thought because I would've thought it was shampoo in my eyes. However, It covered more than half of the shower and had orangish red eyes. I am terrified to go near that shower. Any one know what it is or better how to get rid of it?
