Dreams maintain our mental health

Night terrors are very intense episodes of fright during dreams. These frightening episodes are often accompanied by screaming or yelling, as well as by physical movement such as leaping out of bed or flailing in panic. 

Research suggests that sleep terrors occur during non-REM sleep dreaming, while nightmares tend to happen during REM sleep. 

Studies suggest that recurring dreams may contain more threatening content than regular dreams. Research suggests links between recurring dreams and psychological distress in both adults and children.

According to one theory about why dreams so difficult to remember, the changes in the brain that occur during sleep do not support the information processing and storage needed for memory formation to take place.

While most people report dreaming in color, there is a small percentage of people who claim to only dream in black and white. 

In studies where dreamers have been awakened and asked to select colors from a chart that match those in their dreams, soft pastel colors are those most frequently chosen.

The continuity theory of dreams hypothesizes that people dream about the stuff they're thinking about and doing while they are awake.

Some researchers believe that dreams have a functional purpose that prepares us for difficult or challenging situations when we awake.

The biggest variables that influence your dreams have to do with your regular sleep cycles. If it is a very traumatic event, people will experience nightmares.

People are also thinking more about their dreams, which makes them remember their dreams better.
