Dreams

No one knows exactly why we dream. Everyone dreams but not everyone remembers them. Wether or not someone remembers them, depends on the person. On average you can have up to 4-7 dreams per night which is about 2 hours of dreaming. One theory of why we dream is that the brain sorts out everything from the day. It sorts out what is important and what is not. Another theory is that when we sleep our brain slows down and makes loose connections in our dreams. Blind people still dream. If they were born blind, their other senses are heightened, like hearing, smell, etc. People who became blind after birth still see images. When you see people in your dreams, you've seen them in person. It could simply be a random person in the crowd. In a study, scientists found that people who were learning dreamed more than people who weren't. If someone is snoring, they cannot be dreaming.
