I'm a skeptic but I've been ghost hunting a half-dozen times. And, I mean truly locked in a place that is widely considered haunted by the paranormal community, and we're locked in overnight. These are places like old prisons and psych hospitals.
For all of these cases there were just 3 of us. We go in with a lot of equipment, video cameras, audio recorders, still cameras, etc.
We experienced lots of weird stuff. Unexplained lights and sounds. EVPs. The "typical" stuff if you're a paranormal enthusiast. Now, we debunked a whole lot of those events. A lot of times, something seemed paranormal when it happened but with our equipment, we could figure out after the fact what was going on. Sound can do lots of weird things! Sometimes, it took correlating events at specific times with different pieces of equipment. Either equipment that we left elsewhere in the premises or on us. By comparing different recordings from different locations at the same time, we often could fiure the remaining things out. A drip from one location sounded like a voice in another.
Being skeptics, our goal was to debunk everything that we could. However, there were a few incidents that we couldn't figure out. However, after debunking so much, you really just figure that there must be a normal explanation for those remaining few things. But, my wife and I heard two women talking that we can't account for. We also saw a couple of lights that couldn't be explained. We tried to reproduce it or figure out where the source was, but couldn't. None of that means it's paranormal though, just unexplained.
We never experienced something that was undeniably paranormal, the smoking gun. But, it was a load of fun. I mean, what's not to like about going around creepy old buildings, at night, with just a couple of others, with only flashlights?!
