Strange reptilian dream of an iguana

I tend to have really weird full-colour dreams and usually forget them, and I usually don't bother trying to record them or analyse them, however, the following dream was so vivid and I felt so good about it that I wrote it all down.

Most of my dreams are not set in places I know in this world and do not feature people that I recognise from my waking life, and so it was in this dream. I wonder what it all means and what it says about me?

I had been walking down the banks of a river and wetlands are that came to an end in a lake with reeds. On the sides there were patches of brown dead Duckweed and I was feeling sad that it had probably died from pollution.

I waded out into the water but was very happy to see many large toad tadpoles that were obviously surviving well even if there was pollution present.

I spoke telepathically to someone I couldn't see saying how glad I was to see the tadpoles in the clear water. I think I was talking to the deity or guardian spirit of the place.

I turned and saw what at first I thought was a large Flounder, a flatfish that can live in freshwater, and that I had often seen as babies in the River Taff in Cardiff where I lived in my waking life. It was flat against the rocks that were the same colour but it moved and I could see it was actually an Iguana and not a Flounder.

The Iguana was a greyish-green and camouflaged against the rocky background. It looked at me and then moved upwards out of the water where it vanished from sight.

I next saw a huge statue that was like some form of oriental Buddha or deity from Tibetan Buddhism. I got the feeling it had been there for a very long time and was the deity that presided over the place.

I then woke up with the memories still vivid and feeling very happy. So what did this strange dream mean? Can anyone reading this have a go at dream analysis here?
