* {{Anvilicious}}: Someone involved in the writing process for Dead Meat was absolutely a vegan. There's a rather gratuitous scene of a man eating a bacon sandwich which squeals every time he takes a bite.
** In "The Devil Inside": [[spoiler: The ghosts of the dead victims that couldn't be saved because Allison's stalker was interfering with her dreams (because he thought she was doing the Devil's work) going after the stalker's ghost.]] Allison's faith in her dreams is renewed; the implication being, if they don't come from the devil, whose else could the dreams be coming from?
* BizarroEpisode: The entire plot of the episode "The Man in the Mirror"!
* CrowningMomentOfAwesome: The end of "Wicked Game". And this subtly {{Badass}} line:
-->'''Cynthia Keener:''' You'd be amazed how much the human constitution can withstand.
* EarWorm: In the beginning of the Season 2 episode "The Song Remains the Same", Allison hears ''"I Will Survive" by Gloria Gaynor'' [[TerribleTicking playing loudly in her head]], repeating itself until it subtly guides her to [[spoiler: the iPod of a missing college student who was listening to the song before her abduction]].
* HarsherInHindsight: The episode guest starring David Carradine where he played a spirit that ''looked'' like David Carradine ([[CelebrityParadox who apparently is also an actor in this universe]]). It obviously couldn't be Carradine's ghost since, as Allison states more than once, David Carradine was still alive. Three years after the episode aired, David Carradine died during an auto-erotic asphyxiation accident.
* HeyItsThatGuy / RetroactiveRecognition
** [[{{Series/Supernatural}} Crowley]] shows up in one of Allison's dreams in "Penny for your Thoughts"...in a role not out of the realm of his characterization on {{Series/Supernatural}}
* {{Narm}}: Quite a bit in the later years. Even in the series finale, where [[spoiler:Allison dies abruptly of old age while eating pea soup.]]
* NightmareFuel: Allison gets most of her visions in nightmares...
** In "The Devil Inside", a man claiming to be doing God's work by screwing up Allison's visions, uses an extreme version of this (to be [[DepartmentOfRedundancyDepartment redundant]]) as a last resort to stop her from foiling his plans.
** In the episode ''Will The Real Fred Rovick Please Stand Up?'' the end moment when Mallory Kessinger changes from the ultra-hot Ellen Hollman to [[{{Squick}} a man in a bikini]]. Possibly NightmareFuelStationAttendant material, for those who think it's that way.
* OnlySaneMan: Joe - his wife has these crazy dreams, to which he generally makes reasonable suggestions, only to have them ignored.
* SeasonalRot
** In later years it starts using "And it was all a dream" as a twist a good deal too many times. It also starts re-using other twists from previous episodes.
** Also averted from an episode-to-episode perspective. "Time Keeps on Slippin'" from the "sixth" season is a fan favorite and considered one of the best episodes of the series.
* TearJerker: The series finale.
