As some of you probably already know, I am highly skeptical of most ghost videos on YouTube. Occasionally you do find a gem or two that provides some genuine scary or at least spooky images. These two about a guy who explores old abandoned mines caught my eye. Most of the time when exploring these mines nothing happens. His videos reveal a lot about these old mines and what they used to do. But when exploring one particular mine in Nevada, something weird did happen on the first visit. And then on the second visit towards the end something weird also happens. In the first one, old chains are hanging in the entry area. They were once used to support the platform that moved ore out. One in the rear seems to be moving unusually as if it is being deliberately moved. Of course it might be the result of vibrations caused by walking around the mine or a microquake. The second one appears to have a voice at the end and a what sounds like a French police siren. One likely possibility is that the camera, which records sounds, picked up a transmission that had nothing to do with the mine. Or it could be someone was pranking the guy. Some have suggested perhaps someone lives in that mine and created that message to scare people away. There is also another possibility: that it is all faked to create buzz. Whatever it might me, the videos are fun to watch and appropriate for the Halloween season.
