How i almost lose my Protection IV armor in minecraft

So as I promised, here we are, with a new not-Siren Head story.

So, do you know what the cave sounds are? well if not I'll leave a link to a video as always.

I was mining because I needed Iron ingots for buckets, I was going to the end and I needed to have water in order to protect myself from the Endermen, and large falls. I didn't have much Iron, I found my armor in a village chest, no joke, I found a WHOLE iron armor in a village chest. I was us miming, I had like... 25 ingots and everything was alright, but what I ignored were 2 things:

1. I was mining in a Gravel covered hole in the cave's floor

2. There was a creeper crawling behind me.

For some reason the creeper's hissing and the screeching violin cave sound synchronized, and the creeper exploded, Along with the screeching violin, I fell through the hole, only to find a skeleton, I was half a heart HP, and inches from falling to a lava pit. I ate my last enchanted golden apple, and ran, I built my way over to the top of the now giant cavern, and went out of there, now decided to re-enchant my armor, with blast protection IV and father falling III.
