    The way David thinks longer about the theories involving Hoppers daughter makes me think they are actually going to bring her back into the show at some point and he’s making sure he doesn’t accidentally give it away... 🤷🏻‍♂️

    Upside down is an alternate reality not just a parallel universe the mimd flayer spreads a virus it is the virus.

    I think hoppers daughter is still alive cuz he saw a drawing of a bald girl in the lab (hoppers daughter was bald because of cancer) and he found her stuffed animal in the upside down also she acted very strange in the park similiar to will.

    Why couldn’t she touch any physical people in her mind only the demogorgon she could touch so maybe it was made up in her mind

    About the part with Nancy escaping the Upside down, I don't know if the comics are considered canon, but she was able to escape because Will distracted the demogorgan.
    But I don't know. There are a lot of inconsistencies with the portals.

    I think a reasonable theory is it’s another world filled with monsters. They have access to telepathy and can talk to each other through brain waves which would sprain why they only make noises when there scares and hurt and the thysal hydra doesn’t talk. The monsters also have access to the fourth dimension so they can teleport for world to world. The only way they can feed and get prey is if they find something or someone they can speak to through telepathy and after they have reached there minds they try to get into there mind because once they have go into the mind of a victim they then know what the world looks like and where it might be so they can then open a portal to the world to feed. They upside down also looks a lot like there world because they cans change the manifestation of their world to fit preys like some animals do with their voices. So maybe the monsters, creatures what ever they are all actually highly intelligent beings and now they are getting scared and starting to fight and kill because they have found prey that challenges them in ways they might not have thought,

    I don't understand. When I first saw the Demo-Slug turn into a sort of Demo-Dog, I always thought that Demo-Dogs are younger versions of Demogorgons. Demo-Dogs seem to hunt in packs more often then not, like wolves, then once they reach adult form (Demogorgon), they hunt alone. I forget if the show confirmed if Demo-Dogs are Demogorgons.

    This is not really a theory on the show but you know when your dog barks or at nothing or when your cat just stares at nothing well maybe they are barking/looking at something in the upside down

  • Kaylee Crissey

    The theory on how hoppers daughter could be alive has more evidence when it shows that her tiger (stuffed animal) is in the upside down

  • Pickle Rick
    Pickle Rick 4 days ago

    I personally think that the demogorgon is just an evolved version of the slug that Will barfed out (a.k.a Dart) and the upside down is filled with them (also seen in the game) and you saw how Dart evolved into a Demo-Dog, which is a pre-evolved demogorgon.

  • Amicable Enmity
    Amicable Enmity 5 days ago

    I actually kinda agree with the first theory. It's weird that the Upside Down would have buildings. I mean, who built them if there's no people? What would the rational be for only inanimate objects popping up there? Clearly it was once a perfect mirror of our world, but the Mind Flayer happened to it. Sure, it's "another dimension" but time is the 4th dimension, and they all just build up to the 10th in which all possibilities are viable. Somewhere along all the timelines, ours got entangled with the Mind Flayer's dimension, probably due to Eleven's actions in the first place.

    His daughter definitely IS NOT 11❗️
    Cause his daughter has BLONDE hair and BLUE eyes, and on the other hand 11 has BROWN hair and BROWN eyes💣💣💣
    p.s. I thing his ''daughter'' must live cause MAINLY the moment with her weird look that doesn't match with the whole scene.

    theory: I think the upside down is parallel universe that holds people fears. As you watch season one you will notice that eleven needs to be in a pool of some sort with a much of salt to go to the upside down. but for the other characters they are awake. I believe that this is eleven's fear of what she can become, and her thoughts that her powers can hurt people. And maybe eleven can open a rift between the upside down and hawkins

  • Jke 2013

    Im thinking about the future thing since it all starts when will vomits the baby demodog (witch could be dart) does that mean demodogs evolve into demogorgans
    Also there are no demogorgans in season 2

    Imagine if 11 was actually his daughter but he doesn’t know because he thought she died and she doesn’t remember because she’s been in the lab

  • Hot Nibba
    Hot Nibba 9 days ago +1

    I think the upside down is a world 11 made with her thoughts and how she made it with her thought of the way she’s living and the monsters and just how she pictures bad people and so the monsters and the bad people and the worlds must just be how she thinks the world is because she was treated bad and the monster being (papa) well how she might think of him and she’s just imagined him as a monster and put it in the world and the other monsters and the other people in the lab

    The upside down is a real realm. Study show that it might not be called that but there is a real thing that you do that because if you do something I don’t know what you do but it can take you to a different realm not earth to a “scary” realm or to a good realm that’s not scary. I do think that hoppers daughter is really alive because they did a great job with Wills fake death (if it was not Will I’m sorry I got it wrong I have bad memory) what if she was seeing something when hopper had the flash back his daughter looked terrified she looked like me a lot when I first seen the Demma Gorgon. Also I know we already figured out that you can go to the upside down (just to a different realm) what if anyone else can come to the upside down because Nancy and Eleven went there what if anyone else can. Okay the big monster thing in the sky is based on something a man seen it the sky there’s a lot of videos of it is what I think. A few videos ago that I watched one of the cast members said that all this was based on a true story so what happened to Eleven and a lot more people actually happens today they use them for war but there was a search for one of them that got loose (Eleven) obviously they had to use fake names because it’s private stuff but what if more are out there. Everything that happens in Stranger Things was said to be real so what could have happened? Tell me if you agree in the comment section.

    Anyone else think the show is kind of a metaphor for overcoming childhood trauma? Especially with the few references and eleven having short hair to start with. But just everything else in general as well.

    this isnt a theory i just think it would be cool
    what if elven is some how related to hoppers daughter like yeah what if she was still alive. but wouldnt it be cool if after they faked her death she somehow got powers to? and thats how they somhow got connected and both of there fears *somthing theve seen before in there heads* became the upside down. but they dont know they did it together. thats why eleven says IM the monster. i dont know if i had this right but when hopper was looking for will and found elevens room wasnt that his daughters tiger in there? and thats why it was in the upside down to cuz its her thoughts. this doesnt make any sence but thats just because im tired
    i also ship dustin and nancy

    Here’s a theory:
    Eleven is actually hoppers daughter and the government manipulated there minds into thinking that she died to perform experiments on her. This explains why Hopper and el have such a strong bond. Like if you agree with me

    I have a few theories-
    So you know when El is floating in the pool, she wakes up and starts getting upset? Well Hopper’s daughter freaked out in the park also, and maybe she was seeing something there and didn’t die of cancer. I also feel she is still alive and season 3 will somehow involve her.

    I think 11 is a representation of why exploring mental telepathy or being able to connect to other consciences can be a very dangerous thing. Scientists tell us there's a strong chance for aliens, and other dimensions. So this show is based around the idea that if we gain these psychic abilities...we can either manifest things to life, and/or the massive distances that are in our universe will no longer matter, and connecting invaders will exploit. Just like most of the great Sci-Fi movies, especially the ones of the 80s, they are cautionary tales.
