Daemon's Harrenhal visions in 'House of the Dragon' Season 2, episode 4, explained

While Rhaenyra Targaryen (Emma D'Arcy) and Aegon II Targaryen (Tom Glynn-Carney) battle for control of Westeros, Daemon Targaryen (Matt Smith) is living in his own personal horror movie.

His troubles started in episode 3 of House of the Dragon's second season, when he received a haunting vision of young Rhaenyra Targaryen (Milly Alcock) after conquering Harrenhal. Episode 4, "A Dance of Dragons," kicks these visions up a notch, as Daemon receives not one, not two, but three haunting visitors.
