The clown in my friends basement

(If I add any art it is not mine and credits go to the people just to make that clear)(also sorry if I mess up on grammar)
I based this off the themes where only one person can see someone or something.Ok now onto the real description of the story.
My name is Carson and I have a friend named Carl we've been friends since diapers and we live together and basically we have a basement my friend went down to visit his parents for six weeks on he other eide of the world. I went down to the basement to watch the spare t.v aince the other one isn't plugged in and needs to be fixed as well. So I go down to the basement to see the serial homicidal killer. I yelped in fear he turned around and charged at me I thought he was gonna kill me but when i looked up he wasn't in his clown disguise he just stared at me with hunger in his eyes as my wrists were pinned and I squirmed. I'm the first person to see his real face what does that mean for him and me?
