hanti

Transitive, and the ghost is the subject. Fantomo hantas la domon, not the house is haunted by anything until you say so. If you want the English adjective, use the passive participle: hantita domo, a haunted house, and hantita kastelo, which is the phrase the whole genre runs on. Hantaĵo for the apparition itself exists but is rare enough that most writers just say fantomo.

The register is playful, and it is meant to be. This site keeps hororo as the genre word and hanti as its verb, and both sit in the same corner of the vocabulary as ghost stories, October and children daring each other up a dark staircase. Nothing about hanti is grim. Esperanto keeps its grim words several ranks away and does not lend them out.

The figurative sense came along in the box. A memory, a mistake or a tune can hanti you, exactly as in English, and this is by some distance the commoner use in real Esperanto prose: la demando hantas min is a normal sentence and involves no ghosts at all.
