What Are Dreams?

Have you ever wondered why we have dreams? There are so many theories out there, where to even begin. Some say that dreams are our brain's way of organizing what we have learned in the past in order to better understand what we need to do now and in the future. Others say that dreams are our consciousness experiencing alternate realities or dimensions. Anyhow, there are a bunch of theories we can go over but we suggest you come up with one yourself.
