Platypus dream meaning is explained below using 2 different sources. Each interpretation is shown with its source.

Interpretation 1 — Dr. Mıchael Lennox

The platypus is an incongruous creature with the bill of a duck and a mammal’s body, and yet it is the only mammal that lays eggs. In this way, its medicine applies to being a total original. Platypuses are semi-aquatic animals and yet close their eyes underwater and use a complex system of electrical impulses generated by muscular contractions to maneuver. This connects them to the power of intuition and guidance; they are the animal totem of clairvoyants and psychic phenomena. When the platypus appears in a dream, you are being called to rely on your intuition and innate guidance system.
