I was deathly afraid vampires were going to sneak into my house at night and give me the S U C C. So I used to sleep with a pillow around my neck, as if ol' Count Drac couldn't just yank the pillow away. I also fully believed vampires couldn't come inside unless invited in but that logic didn't get in the way of me still believing they were going to break in somehow.
My mom replaced the hanging toy plane in my bedroom with a realistic white dove. The air conditioning would make it slowly spin around at night and I hid under the covers any time it "looked" at me.
Jesus your mom was out to terrify you lol
