Lolwut?

Okay, I was playing minecraft today and I thought "Hey, I really want to build a secret enchanting room," And since I was at the time trying to make my house into one made of pumpkins I had to make it underground. I didn't want some mainstream ladder to bring me back up though, I wanted something really cool. So I decided to make a piston elevator, an idea that had been in my head for a while. So I set off making my redstone paths, and while burrowing, night passed. I had to go up twice to kill some zombies that were knocking at my door. I was making space for myself to manouevre  and mined a block over my head. The block happened to have a CREEPER standing on it, so when I broke it the creeper came crashing down and I head nowhere to go and ended up blowing up, along with HALF of my house.
