I'm 13, and I still sleep with my parents?

This is a really, REALLY embarrassing confession so I would greatly appreciate it if those out there with mocking comments would keep it to themselves. Okay.... so I'm a young teen and I very rarely sleep in my own room. I sleep in a mattress in my parents room say, 5 times a week and I feel like its really necessary. I'm sort of a horror movie addict, to start y'all in the right trail, and I have watched a huge collection of thrillers and scarring films with my friends in such a young age; I also read horror books. The ring, chucky, the pulse, boogie man, paranormal activity, shutter, the orphan, the stepdad, hide and seek, you name it. I don't know WHY i watch them, but I'm just addicted to them cus they are so interesting and some movies I think is not that convincing or terrifying but when the night creeps in, I get so scared. Like all these thoughts cloud my mind and I imagine all of them and It's like just when I infest my thoughts with the creepy ideas, all these noises like the water leaks and the door creeks happen and i get SUPER paranoid i sometimes breath really loud and go all dizzy. I know, i should not have watched the films but what is done is done and I deeply regret it, but how do I vanish this eerie feeling? To get back in my room and stop sleeping with my parents. And do you think im the oldest of the chain of kids that do this? Thanks for any contribution!
