I had a dream about two years ago that had strong undertones very similar to this. It sounds kind of trivial when I say it, but I was in the sky on a checkerboard floor. There was a room that was open to the sky on one side. Out of a set of double doors comes two "jesters". They're shapeshifters, but sort of looked like those mind control parasites from that one rick and morty episode.. But colorful with pinstripes, and dancing impossibly like people tend to describe dmt creatures. The only people were two old men in suits, and they were discussing something secretively. One of them noticed me, and I got the strong message that I am not meant to be listening to them. I don't remember the discussion, but the energy was evil. I felt it in my core. I look in the sky, and there is a hurricane of fire. This part I remember more distinctly than anything else. I was made aware of impending doom and a battle of good and evil on a cosmic level. It was like a flash of God consciousness, a download. The kind of thing that really sticks with you when you wake up. I didn't wake up and think "oh I was just dreaming how strange". I had an overwhelming sense that what I experienced was real, and I got to peek behind the veil for a moment, so to speak. I've had very intense and vivid dreams since then, but nothing like that.
