Are there really ghosts in the world?

If you believe that human brain waves can exist independently in a space, then "ghost" can be interpreted as: brain waves floating independently in space. After death, brain waves still exist, floating and wandering in space.

This can explain many phenomena about "ghosts".

Why can some people see ghosts and others can't?

This is because everyone sends out brain waves in different places-the brain and brain waves are different. But occasionally there are close. Just like walkie-talkies, two different walkie-talkies can talk to each other by tuning to the same frequency. When a person's brain can receive "brain waves floating in space independently", the brain waves that do not belong to him have an impact on his brain, enabling him to see the dead "people" and communicate with them.

On the other hand, it can't be "damn".

Of course, it can also be that "brain waves floating in space independently" force someone's brain to see "ghosts".

Because of the influence of brain waves on the brain, and because brain waves are invisible, "ghosts" can go through walls. Ghosts can come and go without a trace, and ghosts can perform "magic" and so on, all because of the influence of brain waves on the brain.

Why don't you see "ghosts" during the day and more at night, so it's easier to see "ghosts"?

Because during the day, the ground is irradiated by sunlight, and there are many cations in space, which are relatively strong. And "brain waves floating in space independently" belong to negative ions, which are relatively weak. Therefore, "ghosts" are rarely seen during the day. At night, there is no sunlight on the ground, and the positive ions in space are getting less and less and weaker, while the negative ions of "brain waves floating independently in space" are relatively stronger. It's easy to see ghosts at night.

This is why "ghosts" like to be in dark places.
