A childhood belief about afterlife

When I was little I believed that under all of us and in the core of the earth, that there would be the most evil army of disgusting creatures. Like skeletons or goblins and it was runned by Satan! Every night I got prepared for an invasion of his army. I loaded my Nerf Machine Gun, got my baseball bat ready, loaded my bee-bee gun, and created my own torture weapons if I keep some of them of hostage (only for the night because if my parents would of found out, they would freak). But each night I went to bed, I felt nervous. Because what if they had even better weapons than I could believe and take me as hostage! Then I thought if they came to attack that the rest of the world would be one army. So I felt better and the next morning I was surprised that a lot of things got really wet and messed up and thrown everywhere. My parents told me it was a really big thunder storm. I was really relieved that it wasn't the mayhem of Satan's evil army.
