Dreaming is something that has stumped many psychological scientists and doctors over the years. We do not know for sure why people actually do dream but there are many theories on why we actually dream. Before we discuss the theories on why people actually dream, what is dreaming anyways?


Dreaming is a universal experience that is a state of consciousness with sensory, emotional, and cognitive occurrences during sleep. The person that is dreaming has almost no control of what they dream about. Dreams usually contain emotional experiences that have concerns, dream figures, and objects that relate to the dreamers life.


Here are some facts that you may have not known about dreaming.


  • We may not remember our dreams every day but the average person is thought to dream about 3 to 6 times per night.
  • It is thought that dreams last between 5 to 20 minutes.
  • Around 95 percent of all of our dreams are usually forgotten by the time we get out of bed.
  • Our dreams can help us learn and develop long-term memories.


There are many different theories on what causes us to dream and why we actually do dream. This includes:

  • Representing somebody’s desires or wishes
  • Analyzing random signals from the brain

and the body during sleep.

  • Processing information that was gathered during the day
  • A form of psychotherapy

From new evidence and research, scientists have predicted that dreaming serves many possible functions such as, preparing for possible future threats and helps to develop cognitive abilities.
