Sheldon (Jim Parsons) talks in his sleep and Amy (Mayim) Bialik will be getting receipts in the next episode of "The Big Bang Theory" season 11.

According to the official synopsis, season 11 episode 3 will focus on Sheldon talking while he is sleeping and Amy recording him. She will also attempt to try and convince her fiancé that he has a more chill side. This will result in Sheldon getting stressed out about his upcoming wedding to Amy, especially on their choice for the nuptial date.

Elsewhere on the show, Raj (Kunal Nayyar) and Stuart (Kevin Sussman) become bitter rivals for the affection of Bernadette's (Melissa Rauch) new co-worker, Ruchi (Swati Kapila).

The preview trailer for the upcoming episode shows Sheldon losing his composure about choosing the wedding date for his upcoming matrimony to Amy. He even tells Penny (Kaley Cuoco) and Leonard (Johnny Galecki) that he has chosen 80 dates and instructed them to save all of it until he makes his final choice.

Episode 3, titled "The Relaxation Integration," is directed by Mark Cendrowski. The teleplay was written by Tara Hernandez, Maria Ferrari and Andy Gordon. Meanwhile, the episode's story was written by Adam Faberman, Steve Holland and Chuck Lorre.

In the previous episode of the show, titled "The Retraction Reaction," Leonard gave a shameful radio interview. The university where he works for became furious because he admitted on the radio show that physics research as a profession might be a dead end. His interview also made Sheldon depressed when he realized that Leonard might be correct.

Raj and Howard (Simon Helberg) also felt miserable when they came over to Sheldon's house to discuss the incident with Leonard.

"The Big Bang Theory" season 11 airs every Monday at 8 p.m. EDT on CBS.
