I'm so scared and paranoid!!?

Well i watched scary movies like 2 weeks ago. And i used to love them! like ghost ones but i watched 2 really scary ones and I am so scared of demons and ghost. like my dog will bark in room at random things when i'm the only one home. but we built the house. and it just scares me and im more scared because my best friend that lives in my neighborhood have had demons in her before. But i'm not gonna go into detail. But she lives in the back of the neighborhood by some woods that i think that people have done witch craft before. and im not going to go into detail why. and im always scared at night i cant close my eyes at night unless my mom sleeps with me... idk what to do
