1. **Improves memory:**
* Some studies proved that  sleep aids  in the retention of new knowledge, and there is some evidence that dreaming helps reinforce memories.
* A study was conducted on 99 participants to play a virtual reality maze. The researcher put the participants' memory to test by asking them to recall things in the maze. Half of the participants then fell asleep, and when they awoke, the scientists retested everyone's memory of the maze. People in the napping group performed better on the exam than those in the non-sleeping group. Those who experienced dreams of the maze during their naps improved 10 times faster than the rest of the sleeping group.
2. **Helps you learn and memorize:**
* There is scientific proof that you do learn while being asleep. While you sleep, the brain reactivates and consolidates freshly acquired memories and information snippets.
* According to Harvard Medical School experts, if you learn a skill and then sleep, you may be 10 times better at that activity than if you stayed up.
* Dreaming aids in your brain's processing of new knowledge. Specialists feel that dreams are actively documenting what we need to know and remember rather than just reflecting it. Their findings imply that your dreams are a kind of virtual reality experience in which we watch memory processing.
* Your dreams operate as a “rehearsal” for that new knowledge, allowing our brain to put it into practice and actively organize and solidify it.
3. **Assists emotional healing:**
* According to recent studies, people are more likely to dream about emotionally powerful situations, and theta brain waves during rapid eye movement (REM) sleep are one mechanism for the brain to consolidate such memories. Although what you encounter in your dreams is fictitious, the feelings that accompany them are quite real, and dreams may help you heal those emotions.
* An American report stated that your dream tales essentially aim to remove the emotion out of a given event by forming a memory of it. Therefore, the emotion related to the event is no longer active. This helps you cope with emotions, especially negative ones, which may otherwise promote  stress  and  anxiety  .
4. **Offers a new perspective on things:**
* Dreams do more than just replicate what you have seen or learned; they generate whole new mashups and free linkages between what you have seen and what you know. As a result, your dreams provide a window into your most untamed creativity, as well as new methods of problem-solving.
* Many prominent artists and philosophers who attribute their greatest works to their dreams have testified to this.
5. **Indicates overall health:**
*  REM sleep  is considered the most essential type of sleep. As most vivid dreams occur during REM sleep, lack of dreams indicates sleep deprivation.
* Excessive  alcohol  consumption or intake of REM-suppressant  drugs  such as  antidepressants  may lead to reduced dreams. This in return contributes to  depression  and disturbances in consciousness.
6. **Nightmares do have their share of benefits:**
* Researchers now believe that experiences such as an emotional “dress rehearsal” are the brain's way of preparing you for horrible things that may happen. It is almost as if the mind is expecting unpleasant things and then attempting to come up with answers.
* Some scientists feel this is a primitive protection mechanism; if something horrible happened once, there is a risk it would happen again. As a result, experiencing reoccurring nightmares about that incident may keep you on guard.
