I don't know whether UFOs are real.....but I do know that sentient beings which are unseen by the naked eyes are real....
The oddest thing when it tried to tell you direction of a person by flying across the room and making its energy wave felt in broad daylight in room full of people....I was WTF what was that??!
or when one decided to take a walk at night by crossing the wall right through from the neighbor house....I sit tight as long as they don't bother me. We can coexist with the fish. If they were dead people they should be at rest...poor people. If they were demon I would be glad to give my middle finger up
