What are the factors that stimulate dreams

When people sleep, nerve cells are in a suppressed state, but there are still some cells that continue to operate. These restless cells promote dreams. It is precisely because a few cells are active and have no regularity that the dreams we have are different. There is no logic, and many fragmented dreams will appear. If the accidentally active cells are language cells or exercise cells, then there will be sleep talking or sleepwalking reactions. Therefore, we can no longer think of dreams as a state of complete rest. They are a type of neural activity that is controlled and regulated by the cerebral cortex.

The human unconscious contains a large number of concepts, thoughts, desires, impulses, etc., which Freud pointed out early on. Because of the oppression of these so-called secular moral ethics, our personal thoughts have been suppressed for a long time. Especially when we are awake, we are not even aware of our true thoughts. This is like an iceberg at sea, some sticking out of a corner, and some sinking completely on the bottom of the sea. Dreams are one of the most effective ways we can release these invisible feelings. They are more direct and simple than 'telling the truth after drinking'.

In 'The Analysis of Dreams', Freud proposed four factors that can stimulate dreams: one comes from external stimuli, such as various sensory sensations; there is also subjective thinking, where every flash you make will lead to dreams. The next is physical stimulation, which will be reflected in impact and pain; and the last is pure spiritual stimulation. Of course, today's scientists are still digging and researching in order to get more content.
