I don't know if what I'm thinking of is called Vivid Dreaming or something else. It's when you basically bring your waking conscious mind into your dream. I've had a few of these and one where I went from the dream to fully awake immersed in a total state of ecstasy for an hour and a half! I apparently tapped into "Universal Consciousness/All That Is/God" or whatever you want to call it. But I knew EVERYTHING! Don't ask me to explain, but I did, hahaha.
