Nightmare Fuel / A Haunting in Venice

• The ghost of Alicia Drake popping up in the mirror when Poirot is trying to gather himself in the bathroom, wearing a chilling Death Glare on her face. It's as sudden as it is terrifying.
  • Her reappearance at the end, appearing only in a flash of thunder and then a jumpscare rush at the camera before Rowena plummets to her watery grave. Was she truly a hallucination like Poirot claimed or Alicia's ghost claiming her revenge from beyond the grave? The fact that both Poirot and Rowena seem to react to her appearance suggests it may be the sole real appearance of a ghost in the film.
• The legend of the villa: it was originally an orphanage where the doctors and nurses loved the children there. But eventually the plague came, and infection spread within the orphanage, which caused the adults to leave, abandoning the children who were locked inside, unable to escape.
  • The secret basement. There are what look to be cells, water is leaking in from the canal, there are BASKETS of children's toys that have been abandoned, and eventually Poirot finds a child's skeleton that was left to rot.
• The Holland siblings' Dark and Troubled Past. Nicholas and Desdemona were the only survivors of their Romani village after Germany's mass genocide efforts and had to do anything they could to survive before they were found and rescued by American soldiers. It's never mentioned what they had to do, but Desdemona remarks it was worse than suffering sexual harassment from their boss, Miss Reynolds.
• Rowena's attack on Poirot. All he's doing is trying to bob for an apple, deciding to have a bit of fun, only to be attacked and nearly killed. All because she confused him for Miss Reynolds.
• Dr. Ferrier's story about what he did in the war: he helped liberate a concentration camp. He describes the people there as corpses who came back to life.
  • He's not just haunted by the sights at Bergen-Belsen, although that alone would be more than enough to severely traumatize anyone; he's wracked with guilt over the starving victims who died after being rescued because the medical teams didn't realize that feeding them too quickly would kill them. He's still horrified, even two years later, by the fact that those people survived the horrors of the camps only to be killed with milk by people trying to help them. Unfortunately this is Truth in Television.
• Mrs. Reynolds contacting Alicia's spirit. Even when Poirot begins to break down how she's a fraud, she begins again, looking like a demon as she rushes the camera to channel the spirit.
• Alicia Drake's fate. She died after weeks of agonizing pain and horrific hallucinations, all because her mother couldn't face the idea of her adult daughter having her own life.
