Questions

What i want to know is there are all kinds of dreams, which effects your dreams more, when you have a bad day or a good one? Many people might think that dreams come from mad emotions, but i believe they could also come from bad emotions as well.How does our state of mind affect our dreams? What if your dreams were actually trying to tell you something was going to happen in the future? What if dreams were really the keys to our subconscience? Should dreams be considered important? Why do some people have the same reoccuring dreams? These are all the questions i am going to try to find. They are interesting and they are found to be most common questions people have.
