How will you explain this?

I don't know if I'm crazy or too imaginative but, this happens every time I close my eyes it's like I'm seeing something with my eyes closed..like I don't know if it's a ghost but I'm sure it looks scary..that's why even when I'm taking a bath I never close my eyes. I don't know why this always happens to me..It sucks! I can't even relax with my eyes closed.. do you think I'm crazy?coz I think I am..haha
