I’ve got some unexplained phenomena that happen from time to time at my lab (workplace). Valves closing for no reason, oddly specific equipment failures, that kind of thing. I don’t believe it’s ghosts, but also I genuinely can’t think of any reason for why those kinds of things could happen. I just say that it’s ghosts anyways because it’s fun.

In any case, my belief is that out of all supernatural phenomena to possibly believe in, ghosts are the least horrible thing to believe in, so anyone who believes in ghosts gets a pass from me
