No one has yet discovered the function of dreams in our lives. Some scientists believe that we sleep in order to dream, because dreams tidy all our emotions. Different experiments have shown that people who are sleep deprived present greater emotional disorders (for example, a disproportionate anxiety). Dreams, therefore, bring the psychological balance back. It is very common to have dreams that express anxiety and emotions that you cannot channel in real life. According to Freud, they show repressed aggression and resentment. Many of those, in fact, come from the subject's childhood. So wherever this oneiric anxiety appears, it is advisable to seek the hidden feelings that really cause it. Some beliefs state that anxiety dreams indicate exactly the opposite. In other words, it won't be long until your concerns are resolved. And, in a sense, when the individual expresses their fears in dreams, they get closer to their dissipation.
Types of sleep
There are two types of sleep that most of the humans undergo - REM and NREM. REM refers to the Rapid Eye Movement and NREM refers to Non-Rapid Eye Movement. Every individual will alternate these two types of sleep. Non-REM sleep will occur for a short period of time in the first stage of your sleep followed by the REM sleep. Dreams occur during the REM stage, where it lasts for 20 minutes. According to a researcher, J. Allan Hobson, dreams that occur in REM stage are usually forgotten when the individual wakes up. Studies conducted on patients during sleep shows that the frontal lobes in the brain, that are responsible for storing information, are inactive during the REM stage, which is the main cause for forgetting the dreams. Studies also show that this is the stage where you have the most intense dreams.
