!!This film contains examples of:

* AxCrazy: [[spoiler:Norman]], once everything is out in the open.
* BittersweetEnding: [[spoiler:Madison gets her vengeance by killing Norman and is able to finally move on. Claire is undoubtedly left mentally scarred from everything that's happened, but her visit to Madison's grave seems to imply that she's making steps towards getting on with her life.]]
* BodyHorror: [[spoiler:Madison]]'s decomposing corpse.
* BrokenBird: Claire has shades of this after her oft-mentioned car accident, and there is no possible way she makes it through the rest of the film unbroken.
* [[CatScare Dog Scare]]: How the [[spoiler:seance]] ends.
* ClingyJealousGirl: Madison is painted as one by [[spoiler:Norman]], although it's very likely another lie.
* CreepySouvenir: One of Madison Elizabeth Frank's hair braids.
* DangerousKeyFumble: Claire fumbles with the keys when escaping from the house towards the end, giving [[spoiler:Norman]] just enough time to hitch a ride without her noticing.
* DarkSecret: [[spoiler:Norman isn't quite the perfect husband Claire thinks he is...]]
* DemonicPossession: Claire allows herself to be possessed by [[spoiler:Madison]], which allows her to find out the truth about [[spoiler:the affair]]. She later inadvertently allows another possession as [[spoiler:Norman attempts to drown her]].
* DomesticAbuser: Subverted. [[spoiler: Warren Feur initially comes across like this, but it's all a misunderstanding.]]
* DrivenToSuicide: [[spoiler:Norman claims Madison killed herself when he tried to break off their affair. He's lying. He also intends to make Claire's death look like this as well.]]
* EyeAwaken: [[spoiler:Unconscious Norman's eyes fly open as Claire makes her escape from the house during the climax.]]
* FingerTwitchingRevival: [[spoiler:Norman's fingers twitch as he's lying unconscious at the bottom of the stairs.]]
* {{Foreshadowing}}: Claire having a car accident prior to the events of the film is mentioned a few times. [[spoiler:It turns out she had the accident after driving off in a heartbroken rage after discovering Norman's affair, and the accident left her unable to remember the affair - until Madison makes her remember.]]
* FreezeFrameBonus: [[spoiler:Madison]] is briefly seen reflected in the bath water for a second time (during the "YOU KNOW") scene. She only appears for about a second. Another example occurs at the very end of the film: [[spoiler:as the camera pans down and the screen fades to black, an image of Madison's face can be seen in the snow.]]
* GhostlyGoals: A combination of both Type A and a little bit of Type B: [[spoiler:Madison wants to exact revenge on Norman, but also leaves clues for Claire to lead her towards the truth.]]
* GoOutWithASmile: [[spoiler:Madison's spirit, having avenged her own death, gives a small, peaceful smile as she floats through the lake.]]
* HauntedHeroine: Claire.
* {{Homage}}: Some scenes are an homage to ''{{Psycho}}'' and ''RearWindow''.
* TheImmodestOrgasm: The Feurs' "Sexual Olympics", as described by Norman.
* JumpScare: Several, but perhaps the best example is [[spoiler:Madison's]] first appearance, [[MirrorScare reflected in the bath water]].
** The first time [[spoiler:Claire's face morphs into that of Madison's]] is jarring enough. The ''second'' time it happens - when [[spoiler:Claire's face suddenly morphs into Madison's very dead, very decomposing face]] - is downright ''horrifying''.
* KarmicDeath: [[spoiler:Norman is killed in the same way he murdered Madison - via drowning. Not only that, but he dies in the same lake in which he disposed of her body.]]
* MakeItLookLikeAnAccident: [[spoiler:After killing her, Norman placed Madison's body into her car and rolled it into the lake.]]
* MirrorScare: All over the place. This film will probably make you paranoid about looking into water or bathroom mirrors for a ''long'' time.
* MistakenForMurderer: [[spoiler:Warren Feur.]]
* NightmareFace: [[spoiler:Claire's face morphing into Madison's dead, blue face.]]
* NothingIsScarier: Much of the film runs on this.
* OhCrap: A particularly chilling version happens towards the end, when Claire realises that [[spoiler:Norman most certainly did ''not'' dial 911.]] Later, during the climax, Norman has one when [[spoiler:the very dead Madison ''tilts her head towards him''.]]
* RearWindowInvestigation: Claire towards the Feurs.
* RedHerring: [[spoiler: The couple next door are perfectly nice -- if a bit intense -- and neither is dead or a murderer.]]
* TheReveal: Several, but none are more shocking than the fact that [[spoiler:Norman is the killer.]]
* SnowEqualsDeath: [[spoiler: The film's final scene is of Claire placing a rose on Madison's tombstone, in the midst of a snowy winter day]]
* SpookySeance: Claire and Jody use an Ouija board to try and contact the ghost.
* SupernaturalProofFather: Norman plays this annoyingly straight throughout much of the film.
* TrailersAlwaysSpoil: The trailer ''completely'' spoils the fact that [[spoiler:Norman had an affair with Madison, and by extension also spoils that the ghost is not Mary Feur, but Madison Elizabeth Frank.]]
