Dreams

Dreams are stories and images that our minds create while we sleep. They can be entertaining, fun, romantic, disturbing, frightening, and sometimes bizarre. They are an enduring source of mystery for scientists and psychological doctors.

Are dreams merely part of the sleep cycle, or do they serve some other purpose?
Possible explanations include:
• representing unconscious desires and wishes 
• interpreting random signals from the brain and body during sleep.
• consolidating and processing information gathered during the day.
• working as a form of psychotherapy.
Dreams are a universal human experience that can be described as a state of consciousness characterized by sensory, cognitive and emotional occurrences during sleep. The dreamer has reduced Trusted Source control over the content, visual images and activation of the memory.

    There is no cognitive state Trusted Source that has been as extensively studied and yet as frequently misunderstood as dreaming. There are significant differences between the neuroscientific and psychoanalytic approaches to dream analysis.

     Neuroscientists are interested in Trusted Source the structures involved in dream production, dream organization, and narratability. However, psychoanalysis concentrates on the meaning of dreams and placing them in the context of relationships in the history of the dreamer.
    
    Our most vivid dreams happen during rapid eye movement (REM) sleep, which happens in short episodes throughout the night about 90 to 120 minutes apart. You’re more likely to remember your dreams on weekends or days when you sleep in because each episode of REM sleep is longer than the last. Most of your muscles become paralyzed during REM sleep to prevent you from acting out your dreams.
We may not remember dreaming, but everyone is thought to dream between 3 and 6 times per night. It is thought that each dream lasts between 5 to 20 minutes.
Around 95 percent of dreams are forgotten by the time a person gets out of bed. Dreaming can help you learn and develop long-term memories. Blind people dream more with other sensory components compared with sighted people.
