Most dreams are in color. Most dreams are very meaningful for people. Dreams are useful in learning more about the dreamer's feelings, thoughts, behavior, motives, and values.
Dreams can help people solve problems.
Artists, writers, and scientists often get creative ideas from dreams. The most important thing to remember is that your dreams reflect your own unique underlying thoughts and feelings, and that the people, actions, settings and emotions in your dreams are personal to each person. There may be some dream elements that are common to different persons, cultures, and times because humans have some common traits. For example in the west a lion may represent strength while in the orient a dragon might represent strength. Others are not.
