Chainsaw Sounds

My friends and I were having a sleepover. There was Emily, Carlie and me. around 12 pm, we were laying in bed and heard the scariest sound you could hear. It sounded like a chainsaw. It was not coming from the attic or outside, it was coming from behind my clothes. I ran downstairs to tell my parents, but of course they said it is your imagination. I actually worked myself up so much I got sick. The next morning, my friends claimed it stopped after I went downstairs. We have not had a sleepover together at my house since.

Unfortunately, I will never know what that sound was. I just hope it does not happen again.
