Sleep Deprivation — Tag Meaning
Runs a character past empty — work crunches, vigils, missions, or refusal to face what sleep brings — and harvests the consequences: filter loss, micro-collapses, and truths said in the punch-drunk hours that sober exhaustion can't retract. The trope's destination is almost always enforced rest, administered by someone who cares loudly.

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.

Hurt/Comfort
A genre as old as fanzines: one character is hurt — physically, emotionally, or both — and another cares for them, with the caretaking deepening their bond. On AO3 it spans everything from bandaging wounds after battle to talking someone through a panic attack. The 'comfort' half is essential; without it, the tag is Hurt No Comfort.

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.
