There was a saying: once you were used to strange things, they would no longer seem strange.
There were also some folk legends.
In fact, ghosts had always wandered around us. They simply lived in a different dimension, so neither side could affect the other.
When you told ghost stories at night, they might even gather nearby to listen.
They wanted to see how you arranged their stories.
However.
No matter what you did, there was one thing you had to remember at all costs: never let ghosts know that you could see them.
A soul that remained in the mortal world definitely had something it could not let go of.
But because humans and ghosts did not interfere with each other, even if a ghost moved about in the mortal world, it usually could not influence anything there.
So no matter how unwilling it was to accept things, it could only watch helplessly and wait.
Yet it could do nothing.
However.
If it discovered that you could see it.
Then it would very likely cling to you, making you fulfill the obsessions and wishes it had been unable to accomplish in the mortal world.
That would be very troublesome.
It would loiter in front of you every day, subjecting you to all kinds of mental interference.
Of course.
Mental interference would affect it too.
But that did not matter when it simply did not care!
Think about it.
All day long, you could see someone lying beneath your bed, then see some blood-soaked thing standing on top of your cabinet.
Every morning, the first thing you saw upon waking was a pair of dead hands withdrawing beside your bed.
Every so often, someone would wave at you from outside the window.
Even though you lived on the eighteenth floor.
