It is better to believe that it exists than to believe that it does not exist. There are many things you haven't seen, and there are many things you can't explain. It's not that they don't report, it may be like two worlds. You can't see their world, so it's not easy for them to reach yours! If you happen to see it, then he also happened to enter your space. Why do people hear voices seven days after death? Can you explain it?
