If you see yourself fishing, what did you catch? A small fish indicates small Booty: a big fish, big booty.
The fisherman is trying to catch the content of the soul. Since ancient times, in China fish have been a sign of fertility. As far back as Babylonian times, fish appearing in dreams were considered phallic symbols. According to 2nd century dream interpreter Artemidorus, a dead fish represents lost hope.
The fish is also a Christian symbol.
The point when Spring entered the constellation of the fish coincided with the beginning of Christianity.
The salmon of wisdom is part of Irish mythology.
In psychoanalysis, the fish is a symbol of male sexuality- According to Jung, if you are the fish, you can renew yourself in the Water (emotions). Also, according to Jungian psychoanalysis, the fish is the symbol of wholeness. It symbolizes the total person of the dreamer and, more to the point, the emotional side of sexuality. Jung also believed that fish are like thoughts and hunches, which surface from the unconscious.
(In the fairy tale “The Fisherman and His Wife,” we find the 44 wishing-fish.”) [1]
