I'm gonna recycle a post from a thread seven years ago:

I've had my share of totally weird ones, but two stand out from all the rest. One was just about 50 years ago, with a series of scenes connected by a plot line in which some kind of disease that caused cannibalism appeared and spread rapidly. A real fun dream. I'm not sure which scene was more delightful, the one where the congregation at a child's funeral gathered around the body and started devouring it, or the next-to last scene with a few of us barreling through city streets at night in a city bus, the streets full of the crazed, some of whom were tearing each other apart while others tried to upset the bus and clawed at the windows with bloody fingers. Finally woke up sweat-soaked and a little sick.

The other dream was a short scene, way at the other end of the spectrum, approx 30 years ago. I was along the shore of a little creek at night, watching countless fireflies. That much was an absolutely realistic replay of a beautiful actual experience a few years before. Then a large, shimmering "soap" bubble appeared, floated down close to me, and popped. As it burst, quite naturally with a little moist sprinkle, a voice said "We love you".

Never had a really bad nightmare again.
