A seahorse appears in the dreams of those people who are afraid of drowning, waves crashing against the coast, undersea dangers, currents, and free-spinning whirlpools. When you see a seahorse in your dream, it means that there are pending dangers close by. One symbolic representation of seahorses is for someone or something that can easily navigate waters at will.
The seahorse in a dream can represent swimming or a need for control and power. You might want more control in your life and feel like you’re losing it, or perhaps this dream represents the need for focus or calming oneself during a stressful period or competition by reigning in your vessel.
Another explanation for dreaming about seahorses is that it symbolizes mothers expecting babies when a woman is pregnant. The expectation for birth and rebirth of the fetus means that a change is coming in the dreamer’s life too. The seahorse is one of the few species that mates and gives live birth to its offspring by the male species.
