I have seen two UFOs, but no ghosts.
UFO #1: I was about 8-years-old living in Kansas City, Kansas. I lived in an apartment complex. My room was on the second floor overlooking an empty play area. It was dark, and I was looking at the stars from my window. Suddenly, there was a huge, bright light that passed rapidly over the play area, going from my left to right and heading directly at another building. It looked to be about as big as a small house and only 30 feet away from my window. It was so fast that the whole event was over in less than a second. Even so, I was able to fear that the object was going to hit the other building. Instead, it seemed to disintegrate or disappear. There was no sound and no heat.
The next morning, I ran out to the area where it had disintegrated looking for any kind of evidence that it had been there - looking for dust particles, debris, etc. There was nothing there. Even the cars that were still parked there were clean. At the time, I had thought it had been a meteor that had disintegrated just before hitting the building. But, if it had been a meteor there would have been sound, heat, and debris, but there was none.
UFO #2: I had my own family by then (about 1975), and I owned a home in Independence, Missouri. There was a loud BANG that shook the house! Thinking there had been an explosion, I jumped up to go outside to look for smoke, but there was none. Other neighbors were outside looking too. I went back inside.
A few minutes later, as it was starting to turn dark, I went back outside again looking for smoke - still nothing. However, I did notice what I thought was an unusually bright star. I picked up my binoculars to see it more clearly. I could see two stars – not one. I immediately concluded that it was just the headlamps of an airplane. They were coming in my direction. The plane was going very slowly. For some reason, it seemed odd to me.
It was going too slow for an airplane. I watched it for about 15 minutes - long enough for it to have passed me, but it was still there. Time past, and by then it was completely dark. I could even see the stars. After coming toward me for about 20 minutes, it slowly turned to my right. It was about a mile away from me now, and I could only see a single headlamp washed across the fuselage. The surface was smooth, and there were no markings to read. There was only a single flashing navigation light on the top of the fuselage. Still, there was no sound. I thought that if it were any kind of normal aircraft it would be making some kind of noise. I considered helicopters, props, jets, hot-air balloons, helium balloons, ultra-lights, but nothing fit what I was seeing.
As it continued off to my right over the city, into the dark sky, the image was dominated by two enormously bright, glowing, red lights on the rear of the craft – as if they were the exhausts of two huge jet engines. Each light appeared to be about 16 feet in diameter – much too big for a jet engine. There was no flame as you might expect to see from a jet, and again, there was NO SOUND. From the time I first heard the explosion to when the craft disappeared over the horizon was at least 45 minutes. It was definitely unidentified and it was flying, but I have never seen anything like it since.
Oh, by the way, the next day, in the news, there was a story about a meteor that had entered the atmosphere over the Midwest, and it had caused a sonic boom. So, I guess the explosion could have come from the meteor. I don't know if the UFO was related to it or not.
Ghosts, you ask? - No, no ghosts.
