Dreams can be psychologically beneficial.
Studies suggest that REM (rapid eye movement) sleep is associated with the healing of painful and traumatic emotional experiences. It has been suggested that dream sleep may have the ability to reduce the intensity of difficult emotions, leading to emotional resolution when waking up the following morning.
REM sleep allows the brain to process emotional memories without the interference of the stress hormone noradrenaline. This allows for a safer and calmer environment in which to revisit upsetting memories.
There are five types of dreams:
1.normal dreams
2.daydreams,
3.lucid dreams
4.False awakening dreams
5.nightmares.

NON-REM SLEEP AND REM SLEEP
Some research has been conducted on how sleep may affect emotional responses. In one study, healthy young adult participants were divided into two groups to watch a set of emotion-inducing images while inside an MRI scanner. Twelve hours later, they were shown the same emotional images—but for half the participants, the twelve hours were in the same day, while for the other half the twelve hours were separated by an evening of sleep.
The results of the study showed that those who slept between the two sessions experienced a decrease in emotionality and had reduced reactivity in the amygdala, the area of the brain associated with emotional responses. Moreover, the prefrontal cortex, which helps to maintain control over emotionality, was reactivated after the sleep period. Those who stayed awake did not show the same responses.
We had recorded each participant’s sleep during the intervening night between the two test sessions, and we found that specific brain activity that reflected a drop in stress-related brain chemistry during the dream state was associated with the success of overnight therapy from one individual to the next.
Research has shown that dreaming can be beneficial for individuals who suffer from emotional reactivity, as the emotional content of dreams is associated with a decrease in brain noradrenaline. This was supported by a study conducted by Murray Raskind, which looked at veterans with PTSD and the use of the drug Prazosin, which works as a blocker of the brain's stress chemical noradrenaline. The study found that the vets who took the medication had fewer nightmares and overall fewer PTSD symptoms than those who received a placebo. While additional research is needed, this same effect has been observed in children and adolescents with nightmares.
Research suggests that dreams may help us process challenging emotional experiences, allowing us to learn from them and move forward with our lives.
