Examples of using Dream spell in official material


The Dream spell gained a lot of power in 5th edition, and while perhaps a bit "meh" at a first glance, on a second thought it seems incredibly powerful for a mere 5th level spell (so needs 9th level caster). As I have this spell for a character I am playing, I want to learn more about the lore surrounding the spell.

Is there any published, official(ish) material which makes use of the Dream spell of 5th edition?

Adventures, campaign/setting books, rule books or plain fiction novels, anything like that counts. If it has been given the permission to use the Dungeons&Dragons logo on the cover, it is official enough. Published as PDF only is ok, as long as it is available for download/purchase.

Note: if there is something in some adventure, please use the appropriate spoiler markup for details.

I don’t think there are many cases, so I hope this isn’t too broad a question. I’m just hoping there is at least something.
