My disaster nightmares had to do with the high-tension wires chasing me down lonely roads in the middle of nowhere, screaming like the air-raid siren. Or and earthquake with a total eclipse of the moon. The second one almost occurred with the Sylmar, California, earthquake in 1971. I was three. I still don't like earthquakes, air-raid siren tests, or high-tension wires, but I love eclipses!
