"Stelena" fans will be very pleased when the "Vampire Dairies" returns on Thursday from a brief hiatus with an all-new episode in which Elena and Stefan will share strange dreams about being intimate with one another. In the build up to the upcoming episode, The CW released two new clips and an official synopsis, dropping hints of what to expect.

The trailer for the upcoming installment, "Resident Evil," shows that Stefan and Elena will have vision-type dreams where they share romantic moments together and imagine what life would be like if they stayed together and had children. In one clip, Elena envisions herself flirting with Stefan while their kids play in the background. In another scene, the two share a hot and steamy makeout session on the kitchen counter.

Although fans rooting for Stefan and Elena to reunite will love this week's episode, all of the what-if scenes between the couple are really dreams related to the doppelganger prophecy, reported TV Guide.

In one of the preview clips, Elena and Damon share an intense and awkward moment together in the Salvatore mansion. The scene begins with Enzo opening the door and letting in Caroline and Elena. "I thought you were bringing a witch?" he says to them. Caroline responds, "We said we'd call her, we didn't say we'd pick her up."

Meanwhile, Elena, who appears to be in her own world, immediately asks about Damon who then walks into the room. He can't seem to take his eyes off of her as they exchange an awkward greeting. It becomes obvious that they want to spend time alone talking, so Caroline and Enzo abruptly leave the room.

The other teaser video shows Bonnie paying her boyfriend Jeremy a surprise visit to warn him that there will be trouble on The Other Side. However, while she's there, she discovers that Jeremy and Liv are hanging out and she instantly becomes suscipious.

As posted by Dread Central, the official synopsis for "Resident Evil" states that:

"Both Stefan (Paul Wesley) and Elena (Nina Dobrev) are suddenly having unsettling dreams of an alternate version of the life they might have had together. Bonnie (Kat Graham) has a disturbing encounter with Grams (guest star Jasmine Guy), who warns her about frightening changes on the Other Side. Enzo (guest star Michael Malarkey) gives Damon (Ian Somerhalder) unwanted relationship advice, then admits he is searching for a woman he loved decades before while he was held captive by the Augustines."

The preview continues, "Liv (guest star Penelope Mitchell) enlists Matt (Zach Roerig), Jeremy (Steven R. McQueen), and Tyler (Michael Trevino) to help track the Travelers and keep them from taking control of Mystic Falls. Bonnie is hurt and angry when she learns that Jeremy is working with Liv behind her back. Luke (guest star Chris Brochu) shows up at the Salvatore house and explains what he knows about Markos (guest star Raffi Barsoumian) and the Travelers to Damon, Elena, and Enzo. Matt has a terrifying encounter with inhabitants of the Other Side. Finally, when Damon finds Markos, he is both relieved and disturbed by what Markos has to tell him."

"The Vampire Diaries" S5E17, "Resident Evil," airs on the CW on Thursday, April 17 at 8 p.m. EDT.
