Cave dream

Marked One is having a dream about one of his previous visits to the Cave.
This quest is unmarked and has no official name.
==Walkthrough==
===Doctor's medicine===
Speak to Doctor in the basement by the campfire, and drink his remedy, after which you will be transported into the Cave in your dream.
Look at your feet; there's an artifact and a rucksack. Pick up all items. Insert the battery into the exoskeleton to be able to sprint.
===Making your way through the cave===
The cave can be hard to navigate (but you'll visit it dozens of times so eventually you will learn to do it blindfolded). It contains many fake walls that can be traversed in one direction but not another, which can be really confusing at first. Refer to the main article about the Cave to look at the interactive map.
As everything in the cave is temporary during this quest, you can just rush to Miner's chamber in the shortest path possible, ignoring mutants completely. Here's a video demonstrating that.

===Waking up===
After making your way through the Cave to Miner, talk to him. Drink the vial he gives you, and wake up in the Rookie village basement.
Go speak to Sidorovich to end the quest and recover your gear from the chest near him.
==Notes==
*Your possessions will be put into the stash in the Sidorovich's bunker. You can grab them any time.
*Drinking the vials induces a strong healing effect.
*During the dream, all player stats are frozen, but the time will still pass. It's unnecessary to kill anything in the cave; all mutants will despawn after waking up. It's not possible to take any items back into the reality. There's still a way to exploit it, but you may want to avoid doing this if you're new to this game as the dream is one of the key pieces of the Narodnaya Solyanka story/lore.
* Miner won't talk to you unless you have the following items in your inventory: Assaulter exoskeleton, USAS-12 "Shaitan", Desert Eagle Mark XIX, Porcupine ×5, Emerald Wrenched, Moss, Poltergeist's Heart, Cave map.
* The upper layers of the cave are blocked by a teleport during the dream, and can't be accessed.
* If you're playing on any difficulty other than Nightmare, you're invulnerable during this quest. [Please Test. This does not work as of Build 2.2]
==Bugs==
* Rarely, any of the two vials won't work for unknown reason. If you hit that bug, reload a save. (save the game before drinking)
* Bleeding is not removed after waking up, and you can die from it after finishing the quest.
