Traditionally, a succubus is a female demon who visits dreams. By applying this to a "femboy" (a male-identifying person who embraces feminine presentation), the trope flips traditional gothic horror on its head. It replaces the "predatory monster" with something soft, ethereal, and stylized.

Let’s break down the keyword phrase:

This is not pure erotica — though sexual tension is central. It’s also (what happens if the dream becomes permanent?), slice-of-life (morning-after embarrassment, texting about dreams), and often a quiet trans allegory . Many trans and nonbinary fans read femboy succubus/catboy characters as metaphors for embracing a suppressed identity. The dream becomes the only safe space to be your true self, visited by a being who sees you completely.
