Oneirodynia
noun /ɒˌnaɪərəˈdɪniə/ — Troubled sleep; restless dreaming marked by anxiety or distress.
Definition
Painful or laborious dreaming; the state of sleep in which the mind continues its anxious work — rehearsing conversations, replaying memories, constructing worlds that exhaust rather than restore.
Beyond the definition
Oneirodynia is why you sometimes wake more tired than you went to bed. The brain refused to stand down. It kept rehearsing, kept worrying, kept building and dismantling. You didn't rest — you worked, invisibly.
Origin & history
From Greek oneiros (dream) + odyne (pain, distress). Used in classical medicine to describe disturbed sleep. A word that deserves revival for modern anxious living.

Fictional scene
Anxious Work of the Mind
An adult sits in a dark, somber room, staring intently at a single, empty chair, lost in deep, reflective sadness.
The person’s posture reflects a mind laboring over loss. Like painful dreaming, they are replaying memories and constructing internal worlds of grief that exhaust the spirit rather than allowing for rest or emotional renewal.
