When i was small i watched a cartoon about vampires and i got so scared that i had to sleep with my blanket pulled up to my neck, and i still do it over a decade later.
I also used to think my teddies had feelings. Once i had a toy Husky dog and i had a dream that it bit me. It scared me so much that i put him in the corner of my bed, but because i thought he had 'feelings' i had to throw a blanket over him each night so he wouldnt get angry and bite me lol.
