This is actually a psychedelic trip but I count such experiences as(waking) dreams. I was a stupid, cocky kid who thought he could handle 8 grams dried of Psilocybe Cubensis mushrooms just for context.
15 minutes after eating the shrooms, I began to hear a ringing in my ears ala tinnitus but not painful in any way, my airways opened up and I felt light as a feather walking around, and just a few minutes after that I began to see shadows dancing all around me, both with eyes open and closed that looked a lot like ancient Mayan artwork and as the visual aspect began to intensify, the ringing in my ears slowly turned into what I can only describe as tribal chanting. It was the kind of chanting shamans use to put themselves and others into trance states an the shadows started to appear in more vivid colors, the walls(I was in my parents' house at the time) began to breathe and the shadows began to morph into more complex, colorful fractal patterns, the kinds most often associated with psychedelic experiences.
I put on some Jimi Hendrix and despite the music being greatly enhanced, I could still hear the tribal chanting and other voices began to creep in as well along with my senses getting very much mixed up(synesthesia). Tasting a certain guitar riff, feeling the music vibrate through me like an electric current and around 30 minutes in(hard to say because psychedelics really fuck with your perception of time) everything pretty much went black, and even though I was aware of my body and everything, I broke through/went "out of body" and began to see a tiny, tiny little light begin to illuminate a pure, black void. I was totally unaware of the music playing despite having headpones on, but the small speck of light suddenly exploded into a combination of white and golden light, stars began to form and while I was "out of body", it still felt like I was in my own skin but I coulld fly/float around and observe what was happening.
I have a bit of a blank spot in between the big bang like event and what happened next, but I basically experienced a vision of the universe's creation up until Earth and man came into being, and next thing I know I was floating above Earth next to a gigantic asteroid-like object. It looked kind of like a meteor but it looked synthetic in a way too, like some type of weapon, and UFO-like objects were wizzing all around it as it rapidly began to impact the planet(the object was around the size of the moon), destroying anything and everything in sight until the Earth was nothing but a molten ball completely devoid of life. I felt a sense of great despair and loss, but then I began to see a golden light radiating throughout the entire universe, and it transported me to a place that looked kind of like a star nursery but much, MUCH brighter and more beautiful than the Hubble photos. For some odd reason, I felt nothing but love, peave and comfort in this place and I specifically remember saying out loud "I'm home!" even though I had never seen this place before.
There's another gap after this but I was somehow transported back to Earth right before the meteor struck, but the radiating golden light that transported me to the star nursery seemed to not only destroy the meteor but cover the entire earth in a beautiful, sun-like golden light but it was much brighter and more beautiful than the sun's light when sober.
I count this experience as a dream even though it was drug induced, plus it was absolutely fascinating and scary at the same time, especially because I was tripping so hard that I literally thought everything that was happening during the dream/trip was 100% real and that I was actually dead for a period of time. Psychedelics are fucking powerful, especially when you take way way too much. A normal hard trip dose is around 3.5 grams dried and I took 8. not smart, but at least I have an interesting story!
