Trident — dream trident of Poseidon (Neptune) and experiencing awe - for self-deception. Perhaps what you inspire yourself for 3 years, suddenly driven away like smoke.
To see or use a trident in your dream, symbolizes the God of the Sea. Because of the relation to the sea, you may want to consider the symbolism of water and the ocean. Alternatively, It is also indicative of your creative energies and sensitivity.
