As in the dream you had while sleeping.
Mine had me seeing the sky distort and turn into some sort of dimensional rift. I remember seeing black goo falling from the sky and seeing a large, sandstone ceiling cover everything. Just beyond the reach of clouds I saw a rocky ceiling with square holes in them that lead into the darkness of space. Then, after getting lost in an ancient pyramid, the sky then turned into planets phasing into one another. Like textures in a video game overlapping one another. I saw lights in the sky flying around like fireflies and hearing a voice saying “You’re quarantined on this planet. You may not leave but we can.”
When I was four or five I had this blue and yellow striped shirt that was my favorite, I dreamt I was in a space of infinite white facing myself but it had on a red and green stripped shirt, it said “I’m not making a dream tonight, you do it” then disappeared. My first lucid dream and it was just a dream sandbox of doing and imagining what ever I wanted… was pretty neat. The only other lucid dream I’ve had wasn’t lucid from the start but I was probably 14 or 15, I was shooting a crossbow at a target in the yard when I spotted our violence prone mentally handicapped neighbor behind a tree starting to aim a crossbow at me so I shot him with mine but when it shot it didn’t animate and still was loaded so I thought “really? My dream can’t even animate a crossbow?” Then the dream started to melt from around me into a white space so still upset I decided to just wake up.
Plenty of very vivid nightmares of various levels of gore or death but those aren’t as interesting to me.
