Supernatural's Winchester brothers are officially in over their heads.

'Teen Wolf' Season 5: Graduation Is Not In The Cards [POLL]; Jeff Davis Teases Season 6

Sam (Jared Padalecki) and Dean (Jensen Ackles) have faced off against seemingly insurmountable odds before, but season 11 will put the hunters at a serious disadvantage. This year, no amount of research will be able to prepare Team Free Will for The Darkness.

"The Darkness is pre-biblical," Padalecki cautioned at San Diego Comic-Con, according to TV Goodness. Despite the lack of lore, Sammy will buckle down to try and dig up even the smallest shred of info. "I think his brain is swimming [while] thinking of 'what can we do? How can we fix it? How can I save myself and my brother and the world?'"

When books fail, Dean's little bro will begin to have premonitions - a plot device Supernatural hasn't tapped since season 2.

"He starts to have visions or dreams of a higher power. He's also having memories that maybe weren't memories," Padalecki explained. "Sam believes there's a higher power trying to contact him to tell him how to solve this problem. So it's going to be really cool because we're going to see a few characters via visions that we haven't seen in Supernatural in a long time.'

Is that you John Winchester? After nine years, viewers may finally be reunited with Papa Winchester, although not necessarily in the way one might have hoped.

Are you excited for Sam's new arc, or would you prefer that the supernatural stay firmly out of the hunter's brain? Sound off in the comments below!
