In the subreddit Thomas the Plank Engine, people post the strange memes that they see in their sleep. The surreal humor that comes from dream memes is attractive to all of them, in part because the randomness of dreams makes connections that the waking mind would not. There's not much separating dream memes from intentional humor, but people making up dream memes doesn't seem to be much of a concern to the mods of Thomas the Plank Engine. "Dream memes are made after the fact, based on pieced-together fragments of what you remember from your dreams," they said. To TA10S, the distinction between a "real" meme and a dream meme is even more blurry.
