Answer 2

It's the Upside Down. It's first introduced in Season One when Will and Dustin are racing back to their houses after a Dungeons and Dragons campaign at Mike's/Wheeler's house then the Demogorgon captures Will and takes him into the Upside down. The Upside down was created by 001/Henry Creel/Vecna/ Peter, (technically was created by 011 when she killed Peter.) Who then created the 'monsters' this includes, the Demogorgon (S1), Demodog (S2 maybe, S3) , The Mind Flayer/ Shadow Monster (S3), Vecna and the Demobat's (S4).
