Dream About Creepy Clown Chasing Me

I had this nightmare when I was probably around 6 years old. I can barely remember it, but I’ll try my best to describe it. Everyone was screaming and running all over the place in an attempt to escape something or someone. The sky was red and I was confused. I wanted to know why everyone was running. I stayed where I was so that I might figure it out. Then a clown with blood on his outfit and a knife in his hand appeared in front of me. He stared down at me for a while. He was very unsettling. I started to run shortly after he walked in front of me. Then the perspective changed. I saw myself running as the clown chased me. The clown caught up to me and was about to grab me by my shoulder when I woke up.
