Dreams have always been one of the world’s greatest mysteries; everyone has always wondered why they dream what they dream but not many people have actually sat down and researched about it. I was one of those people, but not anymore. In this research project I will focus on the one question “why do dreams occur?” which will lead me to the deepest part of the brain as I try to figure out the answer. I am proposing this topic because there are various theories about it and not just one big truth; thus with my project, I want to show the reader the different options he/she has as possible theories and then maybe choose one that suits their own experience. I also want to use this research paper to find my own truth about what dreams are and why they happen.
