Dreams are a kind of hallucination that happen during times of sleep. We mostly dream during REM sleep. REM stands for rapid eye movement. In this sort of sleep, you can not recall the dream you had. But it is difficult for investigators to find out about dreams. While you are awake your brain activity work and the thoughts you have are logical. But during your sleep, your brain still works but your body isn’t active so your brain works in an inactive way. So the thoughts you have while sleeping is illogical. Dreams are the autobiographical thinking of your current activities. Sometimes dreams opposing emotional dramas in your life. And because of the regulating of your brain at a much more emotional level than when you’re sleepless, your brain may make alliances considering your feelings that your aware self wouldn’t create. Your dreams can help you to conserve the memories which you have discovered. It is not yet understood how is this possible. But it is quite accurate. Dreams can make us fresh and energetic. It helps to deal with emotion, memories and other thoughts. But the dreams aren’t always positive and good. Sometimes it can be frightening and upsetting, these dreams are known as nightmares. Nightmares can cause stress, negativity, and anxiety. Nightmares can be the reason for sleeping disorders. The reason for this is because you may be anxious before sleep, you have physiological problems and you don’t get the proper amount of sleep. In conclusion,dreams are the embodiment of our unconscious mind.
