Because fish live in water, they have strong associations with subconscious information and the unconscious mind and what’s floating around in there. The image of a fish coming to the surface of water captures the idea of a thought or memory coming into your awareness. See: Subconscious, Unconscious minds Water can symbolize the unconscious mind, so a fish swimming to the surface of water can symbolize that something that was in the unconscious mind is becoming conscious. A fish can symbolize guidance from the unconscious mind. Legends and myths tell of talking fish that give valuable information to people trying to find their way. These stories are allegories for ways that the unconscious mind communicates with its conscious counterpart, and dreams are, in essence, allegories about yourself and your life. See: Unconscious minds Water is also strongly associated with emotions, and the size of the fish can indicate how “big” the emotion is and how much of an impact it has. See: Water A school of fish can symbolize a group of people whose actions, thinking, and perceptions are closely tied together, or who are easily swayed or directed. They engage in “groupthink.” Fish can symbolize options, as in “many fish in the sea.” Because fish swim and the bloodstream has components such as antibodies that travel in it, dreams can use fish to symbolize anything that travels in the bloodstream. For example, in a dream where a fish eats coffee grounds from the dreamer’s knee, the symbolism relates to the body repairing itself—the dreamer had debris in his knee and his body cleared it out while he was asleep. Fish can be associated with the internal pH of the body, since they live in water and bad water will harm them. Fish can symbolize the urinary tract. A woman dreams that she finds a fishbowl in her house with sickly yellow water and three fish dying in it. She then goes about trying to save the fish by swapping out the bad water with fresh water. It symbolizes her internal awareness of a urinary-tract infection coming on. The fishbowl represents her bladder. Pale or lethargic fish can be associated with low energy or lack of vitality—pale means something is missing from the bloodstream, probably related to nutritional deficiency. Fish are considered a healthful food and it’s possible that eating fish, or preparing them as food, is related to your diet and what you consume. See: Eating, Food Colorful fish can symbolize distraction, because it is easy to be distracted by watching them swim in a tank. Fish in water can connect with thoughts, emotions, or feelings, but a “fish out of water” implies someone out of his or her element. More cross-associations are possible with waking life activities like swimming, bathing, and urinating. Fish swimming in murky water can mean that a situation is murky. Fish are associated with Christianity, as a symbol used throughout Western culture. Jesus and his followers were known as “fishers of men,” and one of the most famous stories about him is the feeding of the masses with a few fish and some bread. This symbolic use of fish shows up more in the dreams of practicing Christians, but the stories are widely known and fair game for dreams to use. Ingesting fish in these dreams is associated with Christian teachings. Fish that slip away can symbolize failing to follow something you have been taught—moral teachings in particular. It can symbolize a slippery situation or something you have a hard time holding onto. See: Ice A dead fish can symbolize someone who is unresponsive, especially sexually. It can mean “you’re next,” as in the famous scene with the fish in The Godfather. “Something fishy” is used in connection with suspicion. More plays on words can be made from types of fish. For example, “to carp” means to make petty criticism. “To flounder” means to struggle helplessly. Consider these possibilities, remembering that your associations are the most direct route to the meaning.
