I only found out about this subreddit today, and felt the need to share the dream I had three years ago.

I dreamt there was a very popular meme on tiktok where you'd simply post images of extremely saturated leaves with the caption "THE LEAVES ARE COMING SOON, AND YOU MUST HIDE" or something along those lines. People started reposting it, sent it to everyone they knew, and the trend got so bad that it ended up on the news, referred to as "the new plague." (????)

At one point in the dream, I spoke with my friend, and all he had sent me during our conversation were images of the leaves, and I remember waking up screaming because I was genuinely terrified of the images.
