Dreaming is a series of thoughts, visions or feelings created by your imagination that occur during sleep.
There have been many studies performed on why we dream but scientists are still not 100% sure. There are many theories to why we dream. There is some research to back up the idea that dreams are tied to how we form memories. Some say that we dream so our brain can remember what we learned that day. Studies show that when we’re learning new things in our waking hours, dreams increase while asleep. What we do during the day can be reflected to what we dream about.
On the other hand, a nightmare is a bad dream that brings out strong feelings of fear, terror, distress or anxiety. Nightmares are considered a normal part of childhood. Girls often have more nightmares than boys. They can also continue into adulthood. Nightmares can be a way of our brains to deal with stress we get throughout the day. Some reasons nightmares are caused are because of a major life event like the loss of a loved one, drinking too much alcohol, eating before going to bed and drugs.
There are ways to eliminate bad dreams, though. You can do that by establishing a regular sleep schedule, cut down your caffeine and alcohol intake, avoid eating right before going to bed, exercising during the day, avoid playing violent video games and watching scary movies. If the nightmares really start to bother you, you may have to see a counselor or psychologist to get to the root of the problem.
