When I was young and my episodes of insomnia were already in full swing, I used to sneak and watch *bad* movies on TV - Elvira's bad movies. The most horrific one was about an enchanted tree - or was it a cursed tree, or maybe it was some dude that was cursed and turned into a tree - well, this tree was in love with this woman who screamed a lot and all he wanted to do was rip up his roots, chase her, and eat her. Too exciting. Then years later came Poltergeist. Be still my beating heart.
That damn tree. For years - okay, now still - I couldn't look at a tree at night without palpitations. Not snakes, not spiders - I love how I can love trees and be terrified by them all at once. :D
