You choose the opening

Getting on all fours you begin the process of squeezing into the imperfectly circle tunnel. The opening seems structurally questionable, somehow sustaining itself despite a mass of rocks waiting to topple downward. You have a sense of dread as you crawl through, every time your ass or shoulders bump the walls you brace yourself to be crushed beneath a mountain of rocks.

When you finally reach the other side, rushing the last couple feet out of panic, your foot dislodges a large rock slab that was precariously balancing the majority of the rocks atop it. A tremendous crashing sound is heard and as the dust settles you resign yourself to the fact that there is no going back.

You rise to your feet, knocking dust off your dirtied clothing. You glance around yourself in the black nothingness and it looks to be the most massive room you have ever stepped into.

Suddenly you're having a hard time telling up from down, right from left. You're in such an open space and yet it feels off, the proportions aren't right.

You walk forward, jumping as you can movement to your right. No it was your left? Or was it behind you?

Fright grips your confused state and you run forward, the darkness making you feel like prey running from a predator. Watched. Toyed with. Catching movement in your periphery.

Your running is suddenly interrupted by an unforgiving, cool surface. You smash your head into it and fall backwards, your ass stinging. You look up to see what you encountered and see the face of another person!

You jump back and the stranger does the same. You go to open your mouth only to watch as the stranger copies your movement exactly.

The room clicks in your mind, the dimensions finally making sense. You look to the floor below you, smooth mirror reflects back at you. You dismiss your fear, glancing at the versions of you below, above, and in front of you.

"Why would there be a random room covered by a mirror?" you question the stillness.

You investigate the cool reflective surface once again, trying to discern why it would be here. There is no paneling, no exposed seams between the wall and the floor. As far as you could tell the entire room was smooth. As if this room was all made up of mirror and it had always been here. Nothing about it seemed man made and yet no other explanation made sense!

You stare back at yourself in the mirror, meeting eyes with your contemplative reflection. Something about yourself is so strange. It's you, it has to be you, but something about your reflection...it feels different. You glance down at your body, the stance exactly the same as yours.

You return your gaze to your face, you question why you are amused. What about this situation would make you smirk?

You realize then that YOU are not smirking, but the you in the mirror most definitely is.

Retreating backwards you let out a squeal, the phantom version of you staying still, ignoring the movement you made.

You gaze closer at the smirking version of yourself. It's smirk turns to a sadistic smile and beckons you to stand up. Deciding to embrace the weird in the spirit of escaping this cave, you oblige. Rising to your feet you are now eye level with this reflection, its eyes, perfect replicas of yours but somehow so different.

The Other You points behind its back, taking a step to the right to reveal a doorway. Light spills out of it like a welcome sign; suddenly you know that that is the exit you need. You swivel your head in the opposite direction of the reflection, hoping to see that doorway welcoming you on your side. Unfortunately your are met only by the shadowy oblivion you have been searching through.

Turning back to the Other You, you notice him shakes his head. Communicating that for whatever reason you couldn't reach that exit, yet.

The reflection gives you a glance, a head nod indicating to follow as he leads forward. You follow on your side, **** for some answers. The other you starts to come upon a large chest, beautifully adorned in gold trim. He points at it and then to your side.

You search in the same general direction, coming across a much more decomposed wooden box, the gold trim hidden behind decay. The Other You smiles victoriously and points at you to open it.

You reach forwards, brushing aside dust and grime to uncover a lock.

"It's locked," you tell your mirror self.

The Other You strolls over to the ornate version of the box, hands deftly unlocking his box. Beside you an accompanying click sounds, somehow your box has unlocked as well. You open the lid, your reflection looking on hungrily from beside you in the mirror.

Inside of the box sat two items, each one set behind a locked glass case. Looking closer reveals that the objects in question ignore the surrounding decay. Somehow the box was almost falling apart from age but the cases that help these items shined like new.

Your mirror self motions to you, throwing up a single finger. You get the impression that he is telling you to pick one, a devilish delight shining in his eyes.
