'''[[HaHaHaNo WRONG.]]'''

----
* Several of the ghosts Norman walks by on his way to school died in pretty gruesome ways. For instance, the female pilot was impaled on a tree branch, while the mobster had his feet bound in concrete before being tossed into a body of water to drown, if the fishes swimming around him are any indication. It's all PlayedForLaughs, of course, [[FridgeHorror but it's horrifying if you take a moment to think about it]].
* "''I don't want to go to sleep. And you can't make me.''"
** To explain: The scene is already tense, having Norman separated from his family by the forest literally putting a wall between them. Then he's forced to confront Agatha's ghost alone. Once he finds her, he begins talking to her, and it's easy to hear the fear in his voice. And suddenly, the scene makes a jarring cut right to Agatha's perspective, rushing in towards Norman and stopping right at his ear, pausing for just a moment before her creepy child's voice whispers the above line. At that moment all extraneous sound cuts out; no ambient rustling from the trees, no wind, nothing. Just the sound of Agatha whispering in Norman's ear, with such unimpeded clarity that it sounds like she's whispering in ''your'' ear. And then all hell breaks loose.
* Agatha's ghost form -- a glowing yellow poltergeist made of raw anger and vengeance, who tries repeatedly to terrorize, then ''kill'', Norman to stop him talking to her.
** The way her face and entire body stutters and changes while screaming at Norman doesn't help. It's like you can see her SanitySlippage.
*** Made more disturbing by the fact that it's debatable which direction her sanity is slipping ''in''. She's struggling desperately to maintain her hatred and avoid facing what she's become, although thankfully she eventually fails.
*** The haunting scream she lets out as her head contorts uncontrollably. [[HellIsThatNoise You can't help but shiver while listening to it every time]].
** Also, Agatha's trial. Her [[TearJerker terrified sobs]] and the [[DissonantSerenity totally indifferent]] expressions of the [[WouldHurtAChild adults]] as they sentence '''''a little girl to death''''' are quite chilling.
** Judge Hopkin's composed, matter-of-fact, completely honest explanation for why he had a child killed. "We were scared."
** The raw power she proves to have in her confrontation with Norman. They start off in the forest where she was buried, then she turns it into a wasteland, and then she straight up ''destroys'' the ground, leaving only a few chunks of rock for Norman to cling into.
** After all that Norman wakes up, on top of her grave, where he'd have most likely been found dead if he failed.
* The fact that Norman would have been hanged by the fearful townspeople just like Aggie just for being able to see and speak to the dead.
** Also, the modern citizens of Blithe Hollow are not so different from the zombies who were once Puritans. They tried to kill a child out of misplaced fear as well, and the ''only difference''? They wanted to go for a less antiquated means of executing him [[note]] instead of hanging him, they changed their minds to '''burning''' Norman[[/note]].
** And if they'd succeeded, it's not impossible that Norman would have lashed out exactly like Agatha, becoming a second angry spirit out for revenge. The Warlock's curse, perhaps?
