Do dreams tell you something?

The theory states that dreams don't actually mean anything. Instead they're merely electrical brain impulses that pull random thoughts and imagery from our memories. This is why Freud studied dreams to understand the unconscious mind. Therefore, according to Freud, your dreams reveal your repressed wishes to you. In respect to this, why are my dreams so unrealistic? The content of people's dreams is related to their thoughts and preoccupations in everyday life. Studies show that, contrary to the belief that dreams are mostly bizarre and unrealistic, most dreams involve realistic life situations. The things that people do in dreams also tend to be realistic.

Then, can people read in dreams?

When we sleep, the entire language area of the brain is less active, making reading, writing, and even speaking very rare in dreams. Some people share language-processing ability across both hemispheres, and in some people, it's even concentrated on the right side. You can also ask why do people show up in your dreams? "In Jungian psychology, every person in a dream represents some aspect of the dreamer," Dr. Manly tells Bustle. "The person who 'shows up' is generally symbolic of some aspect of the dreamer's self; other people are simply conjured up by the psyche to offer a symbolic representation of a certain theme or issue."

Consequently, should you share your dreams with others?

This echoes our recent research at the Swansea University Sleep Laboratory which shows that sharing your dreams and listening to other people's dreams can help to improve your empathy levels. There is much evidence that sleep benefits the processing of important and emotional memories.
