Hallucinations — Tag Meaning
Makes a character's senses unreliable — fever, poison, magic, grief, or psychological strain conjuring what isn't there. Fanfic's recurring figures include the hallucinated dead (guilt with a face), the hallucinated beloved (longing with one), and the slow horror of not knowing which version of the room is real; comfort arrives via whoever anchors them.
What to Expect From "Hallucinations" Fics
Unreliable perception rendered from inside; the 'are you really here?' check is the trope's tenderest and most devastating beat.

Fever
Burns through a character's defenses along with their temperature: delirium, honesty without consent, and the fevered murmur of a name that tells the caretaker everything. The fever scene is sickfic's dramatic peak — judgment-impaired truth-telling the patient won't remember, witnessed by exactly the wrong (right) person.

Dreams and Nightmares
The canonical umbrella for significant dreaming: prophetic dreams, recurring nightmares, dreamscapes traversed, and the bleed between sleeping and waking truth. Authors use dreams as subconscious subtitles — what a character won't think while awake plays nightly — and as plot space in canons where dreams can be entered, sent, or shared.

Poisoning
Introduces toxin as plot: assassination attempts, slow doses discovered late, antidote races, and the particular horror of harm that arrives in a teacup. Fanfic favors the configurations that generate devotion — the taste-tester, the character who takes the poisoned cup meant for someone else, the bedside chemistry of an antidote arriving with seconds to spare.

Grief/Mourning
The canonical tag for fic centered on loss and its processing — funerals, anniversaries of deaths, the long ache of absence. Some of fanfiction's most acclaimed character studies live under this tag, as writers give characters the space to mourn that serialized canon rarely allows.
