Can consciousness really leave the body? Why do some people claim that consciousness has gone to another world, scientists explain?

What is consciousness? Consciousness is an abstract term that can not be described by objects. It exists not only in animals, but also in plants, especially in intelligent humans, who have stronger consciousness than other animals and plants.
In science, consciousness is initially interpreted as a kind of response and processing process to the information in the real world. Dreaming, fantasy, reasoning and feeling are all manifestations of consciousness activities. Consciousness can be regarded as thinking to some extent, and is not constrained by the real world.
Human brain can sketch any kind of scene according to realistic elements. For example, it can imagine that it becomes Superman to travel in outer space, leave the solar system, fly through interstellar space, enter the center of the galaxy, and visit another dimensional space. You can also imagine that you can get into the interior of the earth and take a bath in the hot magma.
So what kind of conscious reaction will appear when people are close to death? Brom, a young man, told of his experience of drowning from swimming and having to rely on the trachea and catheter to breathe, but when doctors and nurses moved him, the trachea catheter shifted.
This means that he can't breathe. At this time, Brom feels that consciousness seems to be separated from his body and fly to another world. Brom is ecstatic for this feeling that he has never felt before, because he feels that consciousness seems to be no longer in his body.
"When the mind is away from the body, I am completely engulfed by the light above, and hear the sound of the wind clearly in my ear. After a moment of awe and surprise, I started instinctively sending messages to all parts of the body to let the mind return to the body, trying to shrug, blink and turn around, but it didn't seem to have any effect," Brom said.
Everything seemed to happen at the same time. Time seemed to have lost any meaning to me. Finally, the doctor reinstalled the tracheal tube, started a new breath again, and then the consciousness returned to the body in an instant.
Dr. Sam Pania, from the langney School of medicine, New York University, said recently in the show "Wizard of Oz": many people will come to the same scene when they are in a coma: there will be extremely bright and warm light from above, attracting people to go forward.
This ray of light looks so comfortable that it attracts them like a magnet and they don't want to come back. There are also many people who describe seeing doctors and nurses giving first aid to him when consciousness is separated from his body.
Can consciousness really leave the body and enter a space without objects? In fact, these visions are only a part of consciousness activity. When the human body has no consciousness, consciousness is still active.
So the scene we see is not a sign of the afterlife. It can be explained by modern science. When the body does not obey the command of the brain, the brain may recognize the body as other objects, so it will produce a feeling of separation from the body, but it is not really a part of the mental activity.
