A series of events or images that happen in your mind while you are sleeping .Dreams can be entertaining,disturbing,terrifying or even bizzare .We all dream, even if we don't remember it the next day. Dreams are basically stories and images that our mind creates while we sleep. . They can make you feel glad, sorrowful, or scared(shocking). And they may seem confusing or perfectly rational.
Dreams can happen at any time during sleep. But you have your most vivid dreams during a phase called REM (rapid eye movement) sleep, when your brain is most active. Some experts say we dream at least four to six times a night.A few years after the REM discovery, Michel Jouvet, MD, of Claude Bernard University in Lyon, France, recognized that brain activity during REM sleep resembles that of wakefulness. He called REM “paradoxical sleep” because of the fact that such cognitive activity is accompanied by muscular paralysis. He referred to non-REM sleep, a time of reduced brain activation, as “quiet sleep,” in which there is no muscular inhibition.

Animals probably dream
Many think that when a sleeping dog wags its tail or moves its legs, it is dreaming. While it's hard to say for sure whether this is truly the case, researchers believe that it is likely that animals do indeed dream

blind people may dream visually
In one study of people who have been blind since birth, researchers found that they still seemed to experience visual imagery in their dreams, and they also had eye movements that correlated to visual dream recall.
Some of the most common dream subjects include:
- School dreams (studying, taking tests)
- Being chased
- Flying
- Falling
- Being late
- Sexual dreams
- Being attacked physically
- Dreaming of someone dead being alive, or someone alive being dead
- the person you love or the person you find him attractive
Anxiety and stress dreams
While there is no evidence that we dream more when we are stressed, research shows we are more likely to remember our dreams because our sleep is poorer and we tend to wake in the night more frequently.
studies show the dreams of people with insomnia (a disorder largely characterized by stress) contain more negative emotion and are more focused on the self, in a negative light. Also, the dreams of people with insomnia tend to focus on current life stressors, anxieties and can leave an individual with a low mood the following day.
Can Dreams Predict the Future?
Sometimes, dreams come true or tell of a future event. When you have a dream that plays out in real life, experts say it’s most likely due to:
- Coincidence
- Bad memory
- An unconscious linking of known information
Dream reports of people born paralyzed reveal that they walk, swim, and run in their dreams as often as people without paralysis. Dream reports of people born deaf indicate they often hear in their dreams.
A recent study of the content of nightmares found the most common subjects included:
A recent study of the content of nightmares found the most common subjects included:
- Physical aggression
- Interpersonal conflicts
- Experiences of failure and helplessness
Researchers found fear to be the most common emotion in nightmares and bad dreams, though it’s often accompanied by other emotions as well. Examining the content of dreams is one way to seek answers about the most fundamental question we still must answer: Why do we dream ?
