One explained and one unexplained.
At around age 8 I was standing around outside at night, looking at the moon. All of a sudden in front of the moon flew a giant triangle with a serrated back, sort of like a bat's wing. It made no noise. I was ecstatic and remained convinced that it was an alien spaceship until I saw the exact same craft on television a couple of years later...turns out it was a B-2 Spirit stealth bomber. I guess I had conveniently forgotten that I live about six miles away from a major US Army/Air Force base. Even if it wasn't a spaceship like I desperately hoped it was, it was still a damn cool sight.

At 14, I was staying with a compulsive liar of a friend who claims to have seen ghosts in her house, which was long ago the servant quarters for the large horse farm nearby. Laying on the floor watching South Park while my friend slept, I saw something out of the corner of my eye. I looked at it. It appeared to be a puff of smoke, quite small, about the size of a tomato, sort of off-white with a hint of iridescence. It seemed to roll about an inch above the floor, across the room, under a table, and then dissolved into the wall. I'm sure there's a logical explanation but I can't think of one.

Perhaps
It was a particularly pungent fart. So meaty you could see it.
