Dreams are a code for transmitting information

Everyone has dreams, and dreams are strange, after a long time of research, people find that dreams are meaningful, so they are more interested in the study of dreams.

However, some people think that dreams have no meaning, and that dreams are just that during sleep, the cerebral cortex stops the activity in general, and there are weak activities in a few places, like the scattered stars in the extinguished bonfire, and the images seen during the day appear in front of the eyes out of order. A dream is like a child scribbling with a pen on a piece of paper. It has no meaning.

But they cannot but admit that when a man is hungry in a dream, he dreams of eating; When he was thirsty, he dreamed of water. When a person dreams of hearing a bell, he dreams of a sound that resembles a bell. They believe that if dreams have any meaning at all, they are only that, and that they are a response to external stimuli. This is the view put forward by the Russian physiologist Pavlov, this view is based on the Pavlovian conditioning theory, in the 1950s to 1970s, the Chinese scientific community has been orthodox it, and his view of the dream is also regarded as the only scientific explanation at the time.

There are still more people who think that dreams are meaningful, but their views on the meaning of dreams are varied, but what they have in common is that they think that the meaning of dreams is not its apparent meaning. In the dream, you can fly, can fly up the mountain; People will rob sugar for gems; Ice can turn into gems. Obviously none of this can happen in real life. Therefore, people who believe that dreams have meaning agree that dreams have a deeper meaning beneath the absurd facade. Dreams are like passwords, passing on secret messages.
