Bad dreams

As a kid, I used to get nightmares. Really bad ones. My grandma told my mother to wash an iron key with salt water and put it under my pillow. The nightmares stopped. Dont know how but they did.

As a grown up, I still tend to get nightmares sometimes. Last month I had nightmares for three consecutive nights, and for the life of me, i cant remember what they were about. But on the fourth night I used the iron key for just one night and havent had a nightmare ever since.
