## Continuity

* Tracy Stewart is the second person revealed to have been turned into a Chimera by the Dread Doctors, though she will be mistakenly believed to be a Werewolf until the end of *Dreamcatchers* and will not be officially referred to as a Chimera until *Condition Terminal*.
	+ The first was Belasko, who appeared in *Creatures of the Night*.
* Ethan and Aiden were referenced by Theo Raeken. Ethan was last seen in *The Divine Move*, and Aiden was last seen in the form of a hallucination in *Creatures of the Night*.
* Hayden Romero makes her first appearance as a childhood friend of Liam Dunbar and Mason Hewitt. It is also implied that Hayden and Liam have a negative history that dates back to the sixth grade.
* Alan Deaton examines Belasko's talons and identifies them as belonging to a harpy eagle, the biggest bird of prey. In *Condition Terminal*, it will be revealed that they're actually from a Garuda, a mythological eagle shapeshifter from Hindu mythology.
	+ Deaton also reveals that the only person who should be able to take a True Alpha's power is a Beta of their own making, suggesting Liam Dunbar is the only person who can take Scott McCall's power. This will come into play for the rest of Season 5A
* Mason Hewitt finally learns the truth about Liam being a Werewolf and the supernatural world in general after he saw Liam "wolf-out."
* It is revealed that Theo Raeken can full-shift into a wolf in this episode. It will later be revealed in *Status Asthmaticus* that he can do this because he is a Werewolf/Werecoyote Chimera, and the Werecoyote ability to full-shift into a coyote merged with his Werewolf shapeshifting ability to allow him to fully transform into a wolf.
* Malia Tate begins having flashbacks of the car crash that led to her accidentally killing her adoptive mother and sister, which seem to be triggered when she's driving in a car. The fact that Malia was in this car accident was first revealed in *Anchors*.
* Liam and Stiles find a hole dug in the woods, which Liam falls into while they are following Theo. This will continue to be important through the next few episodes.
* Peter Hale and Derek Hale were mentioned by Scott and Stiles in this episode. They were both last seen in *Smoke and Mirrors*.

## Trivia

* The title refers to "parasomnias," which does not just mean night terrors—in reality, it is a medical term for an entire category of sleep disorders, some of which have already been referenced in the series. This category breaks down further into non-rapid eye movement (NREM) parasomnias and REM parasomnias.
	+ The former category includes confusional arousals (awakening in a confused state), sleepwalking (also known as somnambulism), sleep/night terrors (like that experienced by Tracy Stewart in this episode), teeth grinding, restless legs syndrome, sleep sex, and sleep-related eating disorders.
	+ The latter category includes REM sleep behavior disorder (during which the person acts out their dreams due to a lack of muscle atonia), recurrent isolated sleep paralysis (like Stiles Stilinski experienced while possessed by the Nogitsune), and catathrenia (breath-holding and expiratory groaning during sleep).
