Stranger Things Inspired - The Vale of Shadows Mod: Survival Horror Experience[1.7.10]  

Warning: This mod contains flashing lights which may not be suitable for photosensitive epilepsy. However, the light flashing is not extremely intense.

Note 1. If you have not seen Stranger Things Season 1 and plan to, playing the mod may spoil the horror elements of the show.
Note 2. I will not be answering comments until I finish Stranger Things Season 2. I don't want it to be spoiled!

"It’s a plane out of phase, a world of monsters. It is right next to you and you don’t even see it."

Just like the quote from the show, the Vale of Shadows mod does exactly that. No, it doesn't add a new dimension.
How does it work then?

If you've seen Stranger Things, then you probably have some idea of what this mod contains. For those who haven't, The Vale of Shadows mod is a survival horror experience. As telling you about what it has to offer would spoil the experience, I won't be giving away much details.

Simply start/continue a previous survival world, start surviving as usual, and then proceed to get the daylights scared out of you. And stay alive, if possible.

Enjoy!

Commands:

/gamerule actively_hunt
False by default, if on the experience will be based completely around surviving the monster, and it will appear very frequently. When off, it's not very frequent

/gamerule allow_other_mobs
True by default, if off other hostile mobs will despawn so they don't detract from the horror experience
