I’ve listened to Drunvelo Melchizedek talk about Dolphins and Whales on his Flower of Life series (I found it on Gaia TV). It’s really quite fascinating, the purported origins of these maginificent beings. I hear they also have four brain hemispheres instead of two like us. Their telepathic abilities extend far beyond their communication with just each other from what I understand as well. But who knows.. maybe I’d have to be a dolphin to find out too!
