For me it’s when people make a big deal about the time something happened, like it was exactly midnight or 3am. It has no bearing on wether I believe the story to be true or not but it just makes me wonder why people place so much emphasis on it, it’s like people really believe in the witching hour, if that was the case what happens when the clocks go forward or back, do the ghosts know about that too?

In my experience (currently living in a mildly haunted home) things can happen at any time of day or night. Apart from knowing wether it was light or dark at the time people saw X paranormal thing the time is pretty irrelevant imo.
