Fox's hit TV series Glee is set to premiere an all-new season 4 episode, titled Sweet Dreams, on Thursday.

The highly anticipated installment will feature Rachel (Lea Michele) belting out a familiar hit, Don't Stop Believing, as she'll be using it for a Funny Girl Broadway tryout. Unlike the Glee cast's previous cover of the popular hit, the character is set to mainly perform it by herself, according to Carter Matt.

Rachel's rendition is said to contain the likes of Finn (Cory Monteith), Kurt (Chris Colfer) and the rest of her former club in the background, as she imagines them being there with her. The website also reported that it's still unknown whether Rachel will land the Broadway role or not, which is a similar predicament she found herself in at the NYADA in season 3.

The episode will also show Will (Matthew Morrison) composing the set list for the regionals, and it won't bode well with New Directions.

Roz (NeNe Leakes) will proclaim that she's the new person in charge of the Cheerios, looking to take over for Sue Sylvester (Jane Lynch). Santana (Naya Rivera) will be revealing her heart to Brittany (Heather Morris), and begin her job at the infamous Coyote Ugly bar in New York City.

Sweet Dreams is set to air on Thursday, April 18 at 9 p.m. EDT on Fox. Keep checking back for more of the latest details on the series.
