Weird things are happening in town, and Stranger Things fans have started coming up with theories to explain the show's biggest mysteries. The season finale answered some questions, but asked many more. Keep reading to learn about fan theories that uncover hidden meanings in Stranger Things - but be warned, SPOILERS ahead. These theories may seem far-fetched, but they're surprisingly plausible. Fans of the '80s-inspired series have been working to shine a light on the darkness. Questions abound: Is El really dead? Who are her parents? What's going on with Will and the slugs he's coughing up? Hawkins has seen its fair share of weird events, and things are about to get even stranger. This list explores fan theories, including Chief Jim Hopper's potential allegiance to the bad guys, El's fate, and the true nature of the Upside Down - could it be nuclear fallout or a glimpse of the future? You might even discover some Stranger Things Easter eggs you missed. Born from the show's canon, these theories are hard to ignore, even if you disagree - and you might find yourself re-watching the series to see if you can spot the clues.

The finale shows Eleven (El) is not gone forever.Most fans theorize this.They operate on that idea.Chief Hopper leaves Eggo waffles, a favorite food for a child test subject, in the woods during the season finale. This suggests El did not die.
The Demogorgon did not die either.The Demogorgon lives.Eleven teleported herself away from the monster.This happened...Eleven brought the monster out of the Upside Down before. Hopper left food because he knows El is weak and needs energy.

The situation is simple.The Demogorgon nurtures an egg.The Demogorgon does this when El first finds her. Later, Hopper and Joyce find others; one hatched. This creature stays near Mirkwood because of the egg, incubating victims, maybe to feed its young or keep them contained after hatching.

In the finale, Will coughs up a slug that slides down the sink. Lights flash; he briefly enters the Upside Down. A similar creature came from Barb's mouth when El found her, dead.
This makes Redditor akornblatt wonder if Demogorgons use humans as incubators.The monster did not eat Will or Barb, but it ate the deer.This suggests the Demogorgons use humans as incubators.Stranger ThingsA fan theory asks if Will is infected and incubating more monsters. Should viewers worry about him coughing up that slug? Perhaps it happened before.

This is more of a fun idea than a fan theory.Stranger ThingsThis Easter egg hints El and Nancy have more to do in Season 2. The boys complained 10 hours was too short during their Dungeons & Dragons game; more exploration awaits.Most Stranger Things fans feel this.They mention the cave flowers, a clear sign pointing to the Upside Down entrance at Hawkins National Laboratory.
Dustin asks, "Uh, no, what about the lost knight?" Lucas adds, "And the proud princess?"Yes.One is Eleven, the other Nancy.Stranger Thingsuses the D&D gameto show viewers they have more to explore with both characters. Nancy, Steve, and Jonathan might steal the focus from the boys in Season 2.

"The atmosphere is toxic." A scientist in the finale reveals this about the Upside Down. Why? One theory suggests America and the USSR nuked the world in a parallel dimension—the Upside Down.Stranger Thingstheoriesthat tries to shed more light on the Upside Down argues that America and the USSR managed to nuke the world in a parallel dimension - yup, the Upside Down.
The world is cold and dark. You need a containment suit for any long stay. Could the Upside Down result from nuclear winter? In episode two, they use Geiger counters to search for the monster near Will's house. Consider that.

This theory plays on the Fermi Paradox.Fermi Paradox.: the idea that space should hold life, but somehow, humans have not found it yet.Several actuallyhumans have not encountered it. This theory suggests thatthe Upside Down is a future Earth.This future Earth shows corruption from a 4th or 5th dimensional alien parasite. Every thing in the Upside Down shows this organism. Humans are long gone. People pulled through in 1983 can still talk to the other side, but the parasite will assimilate them eventually.
When someone finds the gate between dimensions, like El does in the shadow veil, they bring the parasite back. Earthlings have little chance. The virus spreads, humans vanish, and toxic air remains. The monster—the Upside Down version of El—tries to hurt the people she usually protects.

Chief Hopper left Eggo waffles in the woods during the final episode. Many questions arose. Does he know she is alive?How Chief Hopper is Eleven's dad?? But this question suggests something else.Stranger Things.theory.goes further. It asks, "Is Hopper her dad?"
The flashback showing Hopper's daughter dying in the hospital ends with a flat line. The scene cuts. What if she did not actually die? What if Hopper put her in a government program to cure her? They took her, against Hopper's wife's wishes, and turned her into Eleven. Hopper learns this only after El disappears and leaves her Eggos in the woods until he finds her.

This one will break some hearts, but one theory suggests El is the monster.Stranger Things.theory.floating on RedditIs El the monster? El says this in Episode 6. El literally says, "I'm the monster." Many viewers think she meant her powers. What if she meant her other side, the dark part of her mind, was actually the Demogorgon?
When the monster vanishes, El vanishes too. Others who enter the Upside Down see it as a dark look at our world. El sees it as just black. This means she exists in that world and ours in a different way than people. Like themonster..

Hopper punches his way out of problems. He suits fighting, whether he likes it or not. But when the G Men show up in the finale, Hopper gets in the car without punching. Did he expect them? Does he already know them from a past life as a government agent?Hopper gets in the car.Hopper gets in the car without throwing a punch. Did he expect them? Does he know them from a past life as a government agent?
Hopper knows where and how to find wires in his home. Thugs interrogate him, but Hopper does not flinch. Hopper disarms guards easily. Hopper has a history.Did he join the government as an agent?Did he work for them before his daughter died?
This man made a deal with Dr. Brenner. Hopper could not guarantee this deal would not end in the death of all the kids. What happens if Hopper works for the villains in Stranger Things?Stranger ThingsSeason 2?

Hawkins National Laboratory lacks a good reputation. Brenner and Co. are shady. The experiments we know include using a child as an assassin and giving hallucinogens to young, pregnant women.We know about using a child as an assassin and giving hallucinogens to young, pregnant women.Experiments include using a child as an assassin and giving hallucinogens to young, pregnant women.
What if some of those hallucinogens escaped?What if those hallucinogens entered the town's water supply?That means Eleven, the Demogorgon, Will's disappearance, and the Upside Down are all just a bad acid trip. What if everyone in town is tripping?
No. That cannot be it.
