To see a monkey in your dream symbolises deceit, insight and intuition. Those around you are working to advance their own interest. Alternatively, monkeys indicate an immature attitude, a playful nature and the mischievous side of your personality. Dreaming that you are attacked by a monkey indicates conflict between your serious and playful side. Perhaps you are procrastinating too much. Alternatively, the dream may mean that you are struggling with keeping your animalistic desires in check.
To see a monkey hanging or swinging from a tree suggests that you are feeling troubled by some issue. To dream of a dead monkey implies that it is time to get serious. You need to focus on some important or urgent issue.
To dream that you are feeding a monkey means betrayal by someone whom you thought cared about your interests.
