What affects your dreams?

Many factors affect dreams. The activities of the day, and especially things you focus on just before falling asleep affect dreams. The subconscious mind also draws on things sensed in real life but not noticed with the conscious mind. Countless other elements influence dreams, from physical conditions in the body - including hormones - to digestion or sore muscles. All of one's memories and images from myths and legends, characters from movies and television, music lyrics, advertising images... in short, everything one encounters throughout life, consciously or subconsciously, can influence one's dreams. Beyond all this, psychologist Carl Jung theorized that each individual is also connected in some psychological or mystical sense to one's family, parents, ancestors and the deep Universal Unconscious.
