Because there’s many ghosts already, and the 2000s ghosts can’t afford rent. This is why most places are NOT haunted. They are officially owned by few older ghosts, but they just rent them out, and the rent is too high to be afforded by most younger ghosts.
And those few that can afford it are too busy for any actual haunting.
Such is life death.
I’m not sure if I should laugh about how much you are playing along or if I should be worried about you
pretty sure it’s literally just that ghosts were a pop-culture thing during that time, like really it was a HUGE thing, everyone was doing seances and hiring mediums, it was completely normal.
Then when the trend faded we were left with the cultural memory of it, associated with the period.
It’s like how disco has some very specific associations.
Personal opinion is ghost story gain credibility over time because people wrote about it or talked about and built a legendarium around the place so when you look into it there is substance it’s not just one guy talking about something that happenned to him.
If it’s just the experience of one person and there are no books or stories about the place it’s just less appealing and stimulating for peoples imagination.
Could be a matter of energy. Perhaps it takes time for a ghost to reform it’s spirit.
LEAVE BRITNEY ALONE!
There have been several short windows in time where the soul pipeline was blocked because of [REDACTED], this leads to a buildup of departing souls and the most [REDACTED] of them end up getting dropped from the backlog database and, bam. Ghosts.
Just never ask them what they saw when they tried to [REDACTED] the [REDACTED]!
If I get to haunt a location when I die, I am totally making dick jokes through Ouija boards and other devices.
