Daydreaming is often a disregarded and neglected aspect of dream study because they are often overlooked as fleeting and wandering thoughts. There is a lack of emphasis on the content of your daydreams. However, the meanings to your nightly dream symbols are also applicable to your daydreams.  he content in your daydreams are also helpful to the understanding of your true feelings and in fulfilling your goals. Daydreaming occurs when you are semi-awake. It is the spontaneous imagining or recalling of various images or experiences 

in the past or future. You allow your imagination to run away from you. When you daydream, you are accessing your right brain, which is the creative and feminine side of your personality.

Daydreams are often viewed as light-hearted in nature. They are just silly fantasies and wishful thinking. Actually, even worrying over things can be classified as a form of daydreaming. When you worry, you are visualizing an unwanted or negative outcome to a situation. By repeating these negative images in your mind, you are more likely to make them happen. Next time you start worrying, try to think of a positive outcome.
