Cultures and Groups: What is the most vivid dream or nightmare you've ever had that you can remember?

When I was a child I would dream about a clown chasing me into the dark woods, wanting to eat my flesh... often I dream that all my teeth are crumbling, like chalk in my mouth... I had dreams about thousands of gigantic nuclear missiles flying overhead and I was trying to find my daughter a place to hide... and most recently I had a dream that that my sister was trying to stab me... am I normal?
