I saw a phantom car a few years ago that had red and yellow blinking lights on the back of it. The thing unique about it was that the flashing lights came from a round grey metallic bar, only barely 1" around and not the normal LEDs or flash tubes. That car went up a street and disappeared, it was never seen again.
And once while staying at a hotel near the airport, I looked out the window one evening and saw at least eight UFOs go out to a point in the air then made a 180 degree turn, and coming back it was no longer a bright white UFO but a small propeller-type plane. I saw that happen about eight tikes until I got bored, but it could have been a dozen UFOs doing that from start to finish. This happened by a major international airport and I could never figure out the point of those maneuvers or where the "airplanes" went to after changing from being UFOs.
One time in 1998, I saw a flock of ducks flying backwards in what must have been a time eddy of some sort.
And on another occasion, I was waiting for the bus and I noticed that this airplane was going toward the airport which was a few miles away, then suddenly it was back some distance away. This wasn't your typical circling the airport for a landing, as the plane clearly didn't fly around in any circle but was like a film that was being reset like in Ground Hog's Day. I watched this strange sight until my bus arrived and figured I had been watching a time loop taking place. I suppose it must have ended sooner or later for that poor unfortunate pilot. So weird.
Those are only just a few strange things that I have seen. My home town has a reputation for weirdness, and the semi-official motto is, "Keeping Portland weird." No kidding...
