Nightmares — Tag Meaning
A small tag with a beloved formula: a character wakes from a nightmare, and someone is there. It flags both the distressing dream content (often trauma- or canon-derived) and, usually, the midnight comfort scene that follows — one of hurt/comfort's most enduring set pieces.
What to Expect From "Nightmares" Fics
Bad dreams rendered on-page and the quiet, vulnerable aftermath. Frequently the scene where two characters first share a bed innocently.

Emotional Hurt/Comfort
A refinement of Hurt/Comfort specifying that the wounds are psychological: grief, self-loathing, trauma, loneliness, fear. Authors use it when no one gets physically injured but a character is in real emotional pain that someone else helps carry. It is a staple of introspective, character-driven fic.

Insomnia
Tags fic built around sleeplessness — characters haunting kitchens at 3 a.m., finding each other awake when the rest of the world isn't. Insomnia in fanfic is less a medical condition than a setting: the liminal late-night hours where guarded characters finally talk honestly.
