When I was very young I watched Watership down, the cartoon film, and I was scared to death by it. So much so that I was convinced that the evil rabbits lived in the basement and any other room that wasdark in the house, I used to scream before entering and fling the doors open really hard to kill the evil bunnies. Suffice to say I didnt like to enter rooms on my own for a looooooooong time
