Mine are often vivid, but not what I'd call complete stories.
Decades ago, I once told someone that I didn't think I dreamed in color. That very night, I dreamed I was walking on a country road by myself beneath a black sky, when suddenly the night lit up with a meteor shower. The trails were shockingly colorful, like, I remember in the dream thinking that such colors didn't actually exist, and I didn't even have names for them. It was achingly lovely. And then I woke up.
I once dreamed that I was an insect, some happy little beetle walking through a forest of grass "trunks". I remember walking beneath a barbed wire fence whose lowest strand seemed like it was miles above me, and then suddenly there was a spider above me, bigger than a T-Rex. It was such a severe, terrifying shock that I sat up in bed.
I once dreamed that I was on Mars, in a cave. There was a woman there who claimed she was a goddess, and she needed to give me a talisman for reasons that were unclear. She handed me a kind of brooch that looked like it was made of amber, with veins of dark bloody color running through it. The closer I looked at it, the more details I could see, like fractal patterns of amber and blood. I remember in the dream thinking that this was a profound gift, the most important thing I'd ever held, and I didn't know how to respond properly to the goddess. I woke up.
Often I dream that I'm being chased through dark, factory-like warrens. Sometimes it's by a T-Rex (a recurring theme of my nightmares), sometimes by something like the Alien in the movie. I'm chased, one step ahead of it, trying to open doors, always managing to stay one step ahead, but never able to slow down. Those are probably generalized anxiety dreams?
