Insomnia — Tag Meaning
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.
What to Expect From "Insomnia" Fics

Nightmares
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.

Late Night Conversations
The tag for fandom's favorite confessional hour: conversations that only happen after midnight, when defenses are down and honesty gets easier in the dark. Kitchen-table talks, rooftop vigils, and hushed exchanges across hotel beds — the setting does half the emotional work.

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.

Sharing a Bed
The broader bed-sharing tag, covering every reason two characters end up sleeping side by side: necessity, nightmares, cold, comfort, or quiet mutual preference nobody examines too closely. Platonic or charged, the shared bed is fanfic's favorite vulnerability laboratory.
