I lived near Vandenberg "Space Force" (formerly Air Force) Base so I saw a lot of weird stuff at times. I think the strangest thing I saw was the plume from when the stages of the rocket separate at high altitude; it's like this weird, wispy-looking thing way high up that just continues to expand because the air is so thin up there it doesn't really dissipate the stuff.
One time, though, I swear to god. I saw this dancing light. It was just going all over the place. I was really drunk though and in college so I might just have had the spins. I still maintain I saw it though. It was about the size of a star light and it was just zipping around all over the place.
Remember the intro credits to Men in Black? It was like the first 20 seconds of that. Just a light zipping around.
I thought I did once but I was in a car not driving and lost sight of it. I've had some awesome ufo dreams though seeing a huge one and night lit up with millions of lights it looked so amazing it's pretty incredible how dreams can feel so real.
