In The Sandman #21, Delirium briefly discusses two humans that she had encountered (supposedly in recent history). There was a man who wanted to kiss her, who she made to see only "pretty colors" (p 14), and a girl who will "always be happy for ever and ever and ever" (p 17).

(Somehow, I doubt the little girl is better off after her encounter with Delirium. I'm picturing something like Joker gas.)

Are these stories told more fully elsewhere in comics (either in the "Sandman Library" or in other comics)?
