Can anyone communicate with the water devas, serpents, mermaids?

Yes. Begin by giving your gratitude and offerings (cornmeal, essences, tobacco, flowers, songs) to the waterways. It is like giving presents to the spirits. As you place your intention on opening communication with the elementals of the water, it will come easier. Elementals can see those with a pure heart.
 

The best way to open to the energies of the spirits of water is to be near the water, open your heart, and engage your imagination. Children are naturals! Remember to BELIEVE! Trust the images, feelings, sensing, or messages that come through. They can be very subtle. Try asking questions like “who can I communicate with if I want to help the waters?” or “how can I help the waters here?” Practice. It may take a few times.
