Do blind people dream?
Dreams in blind people depend on the nature of their blindness. Individuals who have born blind will not have visual dreams instead they have night mares, most of them revolving around their challenges faced during the day. They experience dream through their sensory inputs like touch, smell, noise and emotions. People who were blinded after birth can experience visual dreams based on the visions or images that they have seen.
Improving memory can be done in a number of ways, and one of those is by having a good night's sleep. During sleep, your mind is still busy and going through the process of consolidation, where it strengthen your memories as well as the "practice" skills, which you have learned while you're awake. According to the associate professor at NYU Langone Medical Center, Dr. Rapoport says that something happens while we are all sleeping, and it helps us learn things better. Thus, if you're trying something new, you can perform it better right after you sleep.
