Tread Perilously's look at the USA Network Blue Sky dramedies continues with the Psych episode called "A Nightmare on State Street."

Following his breakup, Gus's sleep habits have become erratic at best and sleep therapist Ashford N. Simpson (special guest Bruce Campbell) offers no real guidance. Instead, Gus's few moments of rest are marred by vivid nightmares of losing Shawn or finding himself in classic horror movie situations. But is all of it a dream? And will Shawn be able to clear guest star Dean Cameron of a murder involving guest star William Zabka? Also, will Tears for Fears' Curt Smith survive in one piece?

Erik imagines a lost 1980s slobs-vs-snobs movie starring Cameron and Zabka. A Psych star plays Secret Mexican, although Erik totally understands why. Justin explains the actual premise of Psych, which is not just "a funny version of The Mentalist." Erik reveals the one thing he really doesn't like about Psych, which leads to a discussion of Topper Returns. Both he and Justin recall an all-day movie marathon they planned featuring Exorcist II: The Heretic. Clive Barker's Texas Barbecue & Great American Steakery becomes a new sponsor. The episode's homage to The Texas Chainsaw Massacre leads to a Tobe Hooper lovefest and Justin realizes Psych is more popular than he thought.
