Dreams occur at a fast eye movement (REM) sleep, when the brain is almost as active as in awake. At the moment, neural networks responsible for memory and emotions are activated. This is why dreams often include events, worries or desires of the previous day. Interestingly, even animals such as cats or rats are also dreaming.
Scientists clarify that dreams also occur during the NREM sleep, which is deeper. But such dreams are usually shorter, less vivid and more like thoughts of fragments than full stories.
Why do we need dreams?
Memory development. Dreams help sort information. The important thing is registered, superfluous, deleted.
Emotional relief. Sleep helps develop emotions, thus reducing the level of stress and allowing you to feel safe to feel strong emotions.
In the brain training. During sleep, the areas responsible for teaching and creativity are activated. That's why the solution to the difficult problem often comes in the morning.
Why are dreams so odd
The brain combines images and impressions into unusual combinations. It's like improvisation. Fragments of memory, emotions and random associations merge in one story. That is why we can be at the same time "at home and universe" or talk to people who have not reached us for a long time. Or even in a dream to see what can happen in the future. But this forecast magic is not, the brain just takes past experience, anxiety, desire debris and modeling possible scenarios.
We don't dream of accidental. It is a natural process that helps memories, emotions and education. Thus, even the strangest dream plots have practical benefits for our brain.
