What do manatees in a dream mean?

I had a dream today that my whole neighborhood was completely flooded. It wasn't bad, beacause everyone was all calm and what not, even though all I can really remember is me. I swam out by the street and two manatees swam by and something told me to follow them, so i did. We swam up and down the street, and played, and they let me ride them and it was really awesome. Then they left because it started raining and I woke up shortly after because the water started turning ice cold. Any ideas other than that this was an amazing dream?
