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.
