Here are some odd ones for you. Not really scary, but it's unexplained:
At the time, I was living out in middle-of-nowhere farmland, on a small plot of acreage. My dad had decided to come for a visit. He had stepped outside for a bit after dark, when I heard him calling for me. I came out with him, and the first thing he told me, was to not turn on the porch light, and watch the shadows.
Now, so you understand the layout, a couple yards from the back door, to the left of the sidewalk, was the garage. Beyond the garage, the sidewalk met with a driveway that led further to the left where there was a barn. There were only two places with light outside around the property: the porch lights (which were off at the time), and a solar light attached to the barn. There weren't even streetlights on the main road. Because of the placement of the barn's light, the garage always cast a shadow over the lawn.
So, as my dad bade, I watched. At first, I had no clue what was going on. I thought he was trying to mess with me, or show me something I wasn't comprehending. Then I saw the shadow from the garage slowly creeping further over the sidewalk. It would inch steadily forward, away from where my dad and I stood, then snap back into place. Then, further out on the opposite of the driveway that intersected with the sidewalk, we noticed a couple of the shadows were doing the same, only creeping toward us. It wasn't a huge movement, but it was an oddly slow one, and just enough to notice if you looked.
My dad confirmed that that was what he'd been seeing, too, and was what made him call me outside.
It was a windless night. No significant moonlight visible in the sky. If the light on the barn was swaying, it would've been a quicker movement, and I believe the shadows would have been shifting in roughly the same direction, not the opposite. If it was bugs, it would've been flittering movements. Could there be something logical I'm missing? Sure, but I still have no clue what caused that, and I only saw it happen that once.
Moving inside the same house, I'd often hear the reverberating thwang of a coil doorstop being flicked, but none of the doors had those kinds of doorstops. I checked. At least twice. I could never pinpoint exactly where it came from, though I had it down to a guess of two particular rooms.
In one of those said rooms, I once had a single waterdrop splash onto my arm while sitting near the center of the room at the dining table. Based on where it landed, I'd say it came from the ceiling. But there weren't any pipes above there that I knew of, and the ceiling showed no sign of water damage. The only thing I was sitting under was drywall and wood. It was the bottom floor of a two-story house, so it couldn't have been a roof leak, though there'd still be the curiosity of there being no visible signs of water above me. All the windows were closed. I hadn't been drinking anything, nor had my hair or hands been wet. The spot was far enough out from my body, and I'd been looking down at my phone, so I didn't drool on myself (hey, gotta consider everything). So that's another unexplained mystery to think about.
Maybe it was all just a trick of the senses. Maybe I missed something in my debunking. Or maybe it was something paranormal. I'll probably never know now.
