Dreaming of water

I had a dream of saving baby turtles there were birds trying to eat them so I through them into the water as fast as I could then I seen a big crab which scared me at first then I seen the birds trying to eat the crabs last baby o I picked the baby crab up and also put it in the water then I got the mom and put it with its baby...

Before the dream was over I was laying at the shallow end of the beach and this big wave came and almost made me hit the rocks I got scared and woke up...

Is it true that you have dreams about water when your pregnant?
