Science has come a long way in using technology to track people in REM sleep to track the dreaming process, but we still have two main questions about dreaming – why do we dream and what are our dreams trying to tell us?

With Medical Daily's review of this topic, we can find answers to help satisfy your curiosity about dreams.

If we consider Sigmund Freud, then we all have a basic understanding that dreams are the product of holding our thoughts.

Followers of Freud strongly advocate the free association technique of lying on the couch while saying the first thing that comes to mind.

However, modern scientists are inclined to believe that dreams "do not actually exist at all".

Other scientists have a theory: the "activation-synthesis hypothesis," which states that "dreams are simply electrical brain impulses that pull random thoughts and images from our memories, and people construct these impulses as dreams in an effort to understand".

Dreams are seen as useful indicators of what is on a person's mind.

A recent study by the group DreamsCloud found that those with a higher level of education tend to dream more often about work-related situations, such as a promotion or dreams of a co-worker, compared to people with less. education.

"We dream about what worries us the most," explained physician Angel Morgan, who led the study.

The more details you can recall, the better you will be able to solve or acknowledge problems in your waking state.

The vivid images we recall in our dreams can also represent our personality traits.

According to LiveScience, researchers from the German Central Institute for Mental Health found that individuals who report dreams in which they commit murder tend to be more introverted, but also more aggressive in real life.

Although there are some naysayers, the connection to human consciousness and dreams is a good thing worth exploring, especially to help diagnose mental illness.

As doctor Sander van der Linden, a researcher in experimental social psychology, wrote, “Dreams seem to help us process emotions by encoding and building memories of them.

What we see and experience in our dreams may not necessarily be real, but the emotions associated with these experiences certainly are."

Because of dreams, we are able to recall memories of emotions without remembering the actual situation that produced them in the first place.

Therefore, we can remember the feelings of love and pain without having to remember our first crush, which later gave us the experience of heartbreak.
