Name of this "I'm so hungry" gag

Is there a name for the gag when a character is so hungry that non-food objects appear as food to them? For example, post #895043, post #829089, post #1008265.

culinary_mirage!

Y'got me. Surprised there's no straight-up mirage tag.

I'm not sure there's a name for that but I'd be inclined to go for "hunger hallucination", "hunger mirage", or replace hunger with "food" for either.

Although post #829089 doesn't seem to fall into the same category as the others.

"hungervision"?

hunger_hallucination gets my vote.
