The Psychology behind dreams.

Why do dreams happen and what do they mean?
My project category I plan to work on this semester is about dreams. Sometimes I wonder why dreams happen, what they mean, etc. I thought that this would be a great opportunity for me to learn more about dreams, I am looking forward to getting a better understanding on how we dream. My plan for my inquiry project is to research about all the different types such as lucid dreams, nightmares, just standard normal dreams, recurring dreams, daydreams and more, what all these different dreams mean, and why we sometimes forget our dreams and maybe even about déjà vu.
