Short horror stories

In the shower

It was a Saturday morning, however, I didn't usually sleep in that much that. I was always the first one awake so I always had to walk down the stairs as quietly as I could to the living room so I wouldn't wake anyone else up. Once I had made it to the end of the stairs, I heard sounds coming from the bathroom. I could hear the water running from the shower.
This was a little odd, considering everyone else was usually asleep. I shrugged it off pretty quickly. I figured it was just my mom or dad just taking a shower early in the morning. They didn't usually do this, but I thought that they could've just had plans or just had trouble sleeping or something like that.
I sat on the couch and turned the tv down on low like I always did. I started to get concerned once an hour went by and whoever was in the shower was still in there. The door was shut, and the water was still running. I was tempted to knock on the bathroom door, but something made me want to just stay seated.

  I stayed as still and as silent as possible. I couldn't even hear myself breath. Time felt like it stood still as he walked out of the house. It had only taken a couple of seconds for him to exit, but it felt like it was minutes. Even after he was gone, I still remained still. I was frozen in fear. I couldn't muster up the courage to move.
  I remained there probably for another ten minutes until I mustered up the courage to stand up. I slowly dragged myself to the bathroom. Blood was flowing down the shower. I fell to the ground in horror once I realized what was happening. Whoever was in my house had to clean up their crime scene. The crime scene was unfortunately my parents...
