Guys I really fucked up and don't know what to do. Please help!

My mom let me have a sleepover with my friends and one of them told me that if you say “Hasan Piker” three times into a mirror it would create an enraged tulpa of Destiny.  I didn’t believe them and to prove it I went to the bathroom, closed the door and said it three times.

The lights cut out and I see something small moving behind me in the mirror.  I’m so scared and the door won't open. Please help!
