Fan theories are a dime a dozen these days. Every Tom, Dick and Harry has some kind of vague opinion on the future of their favorite shows based around tenuous links and often, there's no real evidence to speak of. Every now and again though, one fan theory comes along that will completely change the way that you perceive a show.

As the surprise smash of the summer, Stranger Things has become the subject of more fan theories than most, each of which eagerly dissect the potential meaning behind some of the show's more ambiguous concepts.

What did Will cough up in the bathroom? Will Eleven return in Season Two? And will there ever be justice for Barb? While it appears that this could be the end for everyone's favorite awkward teenager, one particularly impressive fan theory currently making the rounds could reveal the answers to the rest of our questions, outlining exactly what will happen in Season Two.

Unsurprisingly, spoilers will be threaded throughout this article, so if you haven't caught up with the final episode of Stranger Things yet, lock yourself into a sensory deprivation chamber with a waterproof laptop and lose yourself in this gripping '80s nostalgia fest.

So What's The Theory?

Long story short, the internet has deduced that Eleven and the monster are one and the same.

That's right. Thanks to the tireless efforts of numerous Reddit threads, Tumblr posts and fan boards, it looks like we may know now exactly where the Demogorgon came from - the mind of Eleven herself. Uproxx have compiled all of the evidence into one impressive theory that delves deep into the Upside Down for answers.

Here's The Evidence

Throughout the show, audiences are led to assume that the Demogorgon is a monster from another world, one that feeds off the life force of children. After all, when we're first introduced to the creature, it attacks Will and murders Barb a short while later. From the beginning to the end of the show, the Duffer Brothers work hard to make us believe that the Demogorgon is a separate entity who resides in the Upside Down.

However, when we flash back to Eleven's first encounter with the monster, she meets the Demogorgon in an empty, black space that looks nothing like the Upside Down. Rather than journey to a parallel world, Eleven has sent herself inwards, bringing the Monster out of her own consciousness as a result of the training that the Government put her through.

The parallels between Eleven and the Demogorgon are uncanny. During their final encounter, both characters raise their hands to each other as if they were reflections and when the creature disappears, Eleven vanishes too. The poor girl even calls herself the monster at one point, perhaps during a moment of realization regarding the Demogorgon's true nature.

Duality Is A Prominent Theme Throughout Stranger Things

One could argue that stories of this nature often draw deliberate parallels between the hero and the antagonist in order to represent the dichotomy of good and evil. However, the video also points out a number of other clues scattered throughout the show that provide further evidence for this surprisingly strong fan theory.

Early on, the boys describe the monster as a Demogorgon, an actual creature from Dungeons & Dragons that possesses two heads which are in constant conflict with one another. In another scene, Mike refers to a copy of X-Men #134, where the psychic hero Jean Grey struggles to control the power of her evil half, the Dark Phoenix. Then of course there's the Upside Down itself, which acts as a dark mirror image of our own world.

The theory suggests that the Demogorgon is a physical manifestation of Eleven's fear and trauma which has been made flesh by her astounding psychic abilities that the government worked so hard to strengthen.

How Could This Revelation Impact Season Two?

In the first season finale of Stranger Things, Sheriff Hopper delivers some food to a remote place in the woods, including Eleven's favorite snack, Eggo waffles. The smile on his face suggests that Eleven may in fact be alive still and the show's co-creators have since revealed that they left her fate deliberately ambiguous.

For all intents and purposes, it's pretty obvious that Eleven is still alive, and will almost undoubtedly appear in Season Two. The Duffer Brothers would be mad to omit the fan favorite character - but this realisation has darker implications for the rest of the cast. After all, if Eleven is set to return, then her darker half can't be far behind, which means that the town of Hawkins will soon receive another visit from the Demogorgon in the near future.

Some aspects of the theory still require more clarification; For example, if the Demogorgon is a part of Eleven herself, where did the Upside Down come from and how do non-psychics enter that plane of reality?

The obvious explanation here is that the Upside Down really is another physical dimension that Eleven can travel to. Using her abilities, Eleven can punch holes through the fabric of space that other characters can then journey through. However, if that's the case, it's still unclear why the Demogorgon still chooses to lurk primarily in the Upside Down rather than our own world.
