In 1994 I had a nightmare in Paris, France.
I was in a hallway with one-way glass mirrors as walls on either side. I could see two rooms on either side of me through these glass mirrors and each was filled with people in a line. Some of the people were lining up to go on an up escalator, and some of the people were lining up to go on a down escalator.
Then I realized all of them were dead.
A hooded figure with glowing eyes was next to me. It said:
"Life is dangerous. Life is swell. Life is good if you fit it well."
Then I woke up.
