Our brain can remember loads of images we see everyday. These images are stored by a part of the brain. When we are reminded of the incident or the person, our brain reproduces these related thoughts in the form of images. Some people with extra sensory perception experience dreams about future. They can predict the future through their dreams. To experience a pleasant dream, always go to sleep with positive thoughts. These thoughts not only induce good dreams but also give you a fresh start in the morning.
Types of sleep
There are two types of sleep that most of the humans undergo - REM and NREM. REM refers to the Rapid Eye Movement and NREM refers to Non-Rapid Eye Movement. Every individual will alternate these two types of sleep. Non-REM sleep will occur for a short period of time in the first stage of your sleep followed by the REM sleep. Dreams occur during the REM stage, where it lasts for 20 minutes. According to a researcher, J. Allan Hobson, dreams that occur in REM stage are usually forgotten when the individual wakes up. Studies conducted on patients during sleep shows that the frontal lobes in the brain, that are responsible for storing information, are inactive during the REM stage, which is the main cause for forgetting the dreams. Studies also show that this is the stage where you have the most intense dreams.
