Harry Potter and the Philosopher's Stone (novel)/Nightmare Fuel
- The first book is mainly safe-for-reading by innocent souls, but there is a horrifying vision at the end, with Voldemort physically inhabiting Quirrell, his face parasitising in the back of his head..
- Harry is in the library late at night and opens a book. It SCREAMS!
- The three-headed Cerberus acting as the first line of defense for the Philosopher's/Sorceror's Stone is pretty terrifying, even though it is a good-aligned character.
- Something that runs through the whole series, and always have come across as awful at best and nightmare inducing at worst to this troper, is the Dursleys. "No Harry, no one will contact authorities and permanently take you away from your abusive relatives who starve you, lock you up and slander you and your parents. You are being abused for your own safety so if it seems like you will suffer permanent psychological trauma then that's just too bad." Any other child would have been relocated, but apparently the mightiest wizard of our century can't think of any better protection for The Chosen One.
