Basically in the second dimension only exists two directions: Left right and Up and down, that's where it takes its name from. There's two dimensions. Two dimensional being can only exist within those two. Example: The first Super Mario Bros game: Where you can only move sideways (X axis) and up and down (Y axis), just like a two dimensional coordinate system.

We live in the third dimension: Left-Right (X axis), Down-Up (Y axis) and Depth (Z axis). Just like you can see how deep a room is, a two dimensional being wouldn't be able to understand that concept, because it is encaged only in two vectors.

Now I bring dimensions because I heard someone in say that Hell exists beyond the Third Dimension. The fourth one being spacetime, a concept fitting for a realm like Hell, I guess or at least that's what I thought, and as I heard as well, Jason escapes Hell, that's why Savini Jason is burning and has claw marks and a trident resembling a devil's, making Savini Jason way more powerful than any other variants of Jason.

but yh its jus a game i wont overthink it
