I'm scared

   I am trembling as I type this for 'He' has been appearing more frequently now. As He gets more common, his attack methods get more terrifying. He has began stalking me and taking life off me. I heard a strange noise coming from behind me and I span round to see what it was. All I saw was a puff of smoke. A second later, I heard a noise that sounded like somebody screaming but alas, there was nobody there! I heard that scary noise a second time and this time I saw him, but only for a split second. Sadly, I could not take a photo as it wasn't working properly. A few minutes later, I witnesses his terror again. He appeared directly in front of me, screaming at me with a sudden violence and glared into my soul with his beastly, glassy eyes! My point of view shook around and everything went a sickly purple tinge. He disappeared as soon as he had came into sight a moment later and my player suddenly burst into flames! I panicked a plunged into the cold, soothing water. Before he vanished, I pressed print screen, but only captured the smoke he left behind and the purple coloring of everything. As you can see, he was unnervingly close to me.

When I had recovered from my terrible experience, I walked round my island. I was surprised to find several blocks of glass leading into the ocean. What is Herobrine doing?
