Dreams are a fascinating and complex phenomenon that has puzzled people for centuries. Although the exact purpose of dreams is not yet fully understood, researchers have put forward several theories as to why people dream. In this article, we look at the possible purposes and meanings of dreams.

Biological and psychological background of dreams

Dreams mainly occur during REM sleep (Rapid Eye Movement), when the brain is most active. During REM sleep, the brain’s electrical activity resembles that of being awake, and this stage is important for learning, memory, and emotion regulation. Several theories have been put forward about the biological background of dreams:

  • Memory consolidation: Dreams can help the brain process and organize information learned during the day. This process can improve memory and learning ability.
  • Emotion regulation: Dreams can act as a way to process and release emotions. This can help people cope with stress and traumatic experiences.
  • Brain training: Dreams can provide the brain with the opportunity to practice different scenarios and problem solving in a safe environment.

Symbolism and meanings of dreams

Dreams are often full of symbolism and can reflect subconscious thoughts and feelings. Psychologists such as Sigmund Freud and Carl Jung have proposed theories about the meanings of dreams:

  • Freud’s theory: Sigmund Freud believed that dreams are a way into the subconscious and reflect repressed wishes and fears. According to him, dream symbols can reveal deep psychological truths.
  • Jung’s theory: Carl Jung, on the other hand, believed that dreams are connected to the collective unconscious and contain universal symbols that are common to all people. According to Jung, dreams can help an individual understand himself better and achieve psychological balance.

Dream research and modern science

The study of dreams has progressed considerably in recent decades, and modern science offers new perspectives on the purpose of dreams. For example, neuroscientists have discovered that dreams can be the result of random electrical activity in the brain that connects memories and experiences in a new way. This may explain why dreams are often strange and illogical.

Although the exact purpose of dreams is not yet fully understood, it is clear that they are an important part of human psychological and biological functioning. Dreams can help us deal with emotions, learn new things and understand ourselves better.
