It's not specifically about dreams, but you could probably call it an inverted The Un-Reveal.
From its Playing With page under Inverted: "The information is revealed to the viewer, but not the characters."
(In your example, I'd say forgetting the reveal immediately is the identical to having never seen it.)

It also counts as a played with version of Trauma-Induced Nightmare.
Current Project: Incorruptible Pure Pureness
Is there a trope for a character who has trauma based amnesia, dreams about his past but always forgets it in the morning?
