Sam Winchester's dreams aren't what they appear to be. According to Supernatural co-showrunner Andrew Dabb, Sam's "weird dreams" will play a big role in the show's fifteenth and final season, so much so that it will get a few other characters involved.
“As they keep happening more and more, I think it’s going to dawn on [Sam that] this may be more than just PTSD,” he told TVLine. “Once Sam realizes what’s going on here, there are a couple people he will try to reach out to, some you may be expecting, some you may be not.”
Back in the first two seasons of the show, Sam occasionally found himself dreaming about the future. For instance, he saw his girlfriend Jessica's death in dreams months before it happened. These powers appeared to be tied to the Yellow-Eyed Demon, aka Azazel, as part of his plan to turn Sam into the perfect vessel for Lucifer. They stopped after Sam and Dean successfully defeated Azazel in the Season 2 finale.
In his tease, Dabb didn't offer any clues about who Sam will contact. Following the deaths of Arthur Ketch and Rowena MacLeod, their list of allies continue to dwindle -- and whoever he reaches out to will likely find themselves in trouble before long. After all, they picked a fight with God, and now he isn't going to bring anyone back.
Airing Thursdays at 8 p.m. ET/PT on The CW, the final season of Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert.
