She is inside me

Megan knew this day would come, she just didn’t think it would happen today of all days!
Hi my name is Megan this might be weird but have a evil twin inside me he name is Maggie she thinks her destiny is to rule the world. Normally she tries to control my body coming in my thoughts its driving me insane.I had a dream a few days ago when she got so strong she came out my body from my mouth but then I died and woke up. But its just a dream, but I don't mind to nights my prom and the cutest boy in the school Stephen is taking me.
At the prom my stomach was hurting and I did not want to throw up on Stephen so I did not dance with him when suddenly my mouth started to open and I stated to scream but then Maggie shut up or ill kill you just like in your dream. Then i felt a lick on my face it was Stephen he licked me but it was my dog dojo he woke me up, it was just a bad dream I hope the prom is this Friday.
