I never had a basement, but for a few years while I was in grade school, I lived in this old house with an attic. I used to believe there was a mystical dragon living up there, and that if I could steal a necklace it protected it would grant me seven wishes. But I was always too afraid of it, and at night the house would creak and groan, and I'd think the dragon was eating the last person who tried to steal the necklace.
