A joke in a dream is a symbol of mirth and laughter in much the same way that it is in your waking life. It is important to note who is telling the joke, and who is receiving the joke in the dream. Sometimes a joke in a dream or something funny in a dream is a simple way of relieving stress, much like it is in waking life. If the joke in the dream is associated with particularly good feelings, know that the person associated with that feeling in your dream is important to you in your waking life. If a joke is being played on you, or you are the butt of a joke, the negative feelings associated with that could suggest some insecurities on your part. Examine the nature of the joke and the details surrounding it to determine where those insecurities in your life may be at this point in time.
