So here i am, im going to share what REALLY happened on the music disc 11.

(Minor Warning: Long Article)

This is based on the realism of the situation, not a cartoony-type answer like "Tacos killed steve while he was mining"
To follow go here:

Now to get started.
ANALYSIS:
0-9 Shivering and walking into a cave with ambient noises. this shivering means he could be in a taiga biome.
10- sits down, backpack/gear heard hitting the stone
10-18: heard dragging out tied flint and stone, making rattling noise.
18-20 striking flint and steel.
20-27 pages heard flipping. possible backstory. Coughing.
27-32 Stomping. stomach growling indicating he is hungry.
32-35, puts something on stone, sigh.
35-43 Pages flipping again. Possible backstory.
43-46 Deep breath indicating he found something.Strikes flint and steel 2 times while spiraling noise builds up.
46-1:00: Running towards ouside of the cave. makes it out.
1:03: Broken wavelength call for *HELLP HELLP*
rest is broken record sounds.

Possible Explainations:
(Note, Most Popular theories.)

#1
(Person) went into a cave because he was cold and sick
(Person) Figured out how to light fire with flint and stone.
(person) lit the fire and with the fire's light shined on something/someone,(Person) starting running out of the cave,but the something/one caught up to him, and (person) cried help til his life ended.

#2
[COMMUNITY PROVIDED THEORY]
An adventuer walks into a cave with a  metal enigma watch, replacing the flint and steel.
he soon drags out a book, and figures out how to crack the enigma.
he crack the enigma and two bright white eyes on the watch glow.
he soon hears something running towards him and cries help.

#3
[COMMUNITY PROVIDED THEORY]
Herobrine went out mining one day. He walked along the mineshaft tunnels, sharpening his pickaxe. Then he stopped. Diamonds! Raising his pick above his head and waiting for the time to strike the ore, Herobrine coughed a little, to check if anyone else was around. Then he swung the pick down on to the diamond, shattering the stone. He also shattered his favourite disc, codenamed Disc_11. Shards of the disc mingled with the glowing diamond, and hit Herobrine in the eye. His eyes turned white and glowing. But the disc was broken. he buried it deep in the rock, with it still fizzing from the broken electric, and left it there. After this experience, Herobrine tries to stop players from finding diamond by shooting fire at them. the cave in which he found the diamond is now Herobrine's cave.

We will try to test these theories, and use evidence and in-game proof to what REALLY happened.

Some finds:
11 and 13 are considered REALLY UNLUCKY to some.(except Italy) coincidence?

Wavelengths at the end show the face of herobrine and the numbers (12418)




So we're dealing with herobrine somewhere in here.

12418 is the mark of that of C418. the maker of the disc music.
1+2=3 and C is the equivelant of 3. C418.

Now, We could go ahead and mark off Theory #3. 
There is no sounds of that of a disc breaking, or stone being broken (it sounds like smashed concrete)
and no sounds of Fire roaring.
So 3 is mostly NOT the real explanation.

So for 2: We do have video evidence this could happen with everything on the disc falling into place.
but its a mystery cloacked in mystery. what's the enigma device do? why does he go into a cave?
for this we would need some explaining. the enigma device does reference the eyes of herobrine. maybe an alternative to the herobrine spawner? we dont know. Heck, it could be a freaking chicken spawner for all we know. if anyone has any Evidence of anything the machine does, comment about it.

and for 1: It could be referencing to the first seen photo of herobrine.


As Fog is known to decrease temperature (not by alot, but still, if you had purple jeans and a turqouise t shirt...) (Shivering) and Sometimes, if it is radioactive or some other fog, breathing problems. (Coughing/Sneezing)
This is by far the most popular theory, as it is what most people think of after hearing the disc.
oh and btw anyone see the 13 wood blocks?

Anyways, The bait is going for Number 1 by now. (References, Proof, and overall popularity)

So id did some experiments in minecraft. i think i figured out what happened.
STORY TIME!

It was foggy, Steve was cold, and more or less sick. he seeked shelter and for warmth. he went into a cave and set down all of his stuff. He pulled out his flint and steel, striked it, but no sparks came out. he soon coughed and went to get his book on how
to start a fire he wrote beforehand. he pulled out his book, and soon realized how to create the fire. He started the fire, and out of the corner of his eyes he saw herobrine. He quickly tried running, but wasnt fast enough and looked back to see the creature right in front of him. se soon yelled HERO-BRi--.-  and the disc ended.

If you disagree with what i figured out, please comment. but dont make a fool out of yourself.
