The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Alternatively, could be a subversion of A Form You Are Comfortable With. I recall an episode of Doctor Who where the TARDIS's computer projects a hologram to help the Tenth Doctor while he is slowly succumbing to a poison and chooses to take the form of someone familiar to him, to which he complains something along the lines of "choose someone that doesn't make me feel guilty to look at!"
I was going for something that could be considered a super-trope of Ironic Hell; instead of a punishment that fits a crime, this is more like, "whatever the person will find most unpleasant". Like a boggart from Harry Potter - it has no form until someone sees it, then it becomes what that person is most afraid of.

Seconding Personalized Afterlife for the general idea of a personalized hell.
Appearance Is in the Eye of the Beholder is in play here as well- each sees the same environment in a different way at the same time.
You Cannot Grasp the True Form is involved, too, as each is seeing the hellscape and its denizens in a metaphorical way they can relate to.

A hero and his sidekick break into Hell to rescue a demon's hostage. Turns out Hell is what you hate most. The chisel-jawed hero sees an overgrown field full of feral beasts. "I was stranded in the Serengeti in an aircraft crash. Had to survive in the wilderness for three months before I was rescued." His sidekick sees an office building full of stony-faced bureaucrats. "I was a temp before I became your sidekick. Everyone I worked for would rather stare at me than pick up their own garbage." The hero sets his jaw. "...Fiends."
