I heard a herobrine story:
Long ago, there was a boy named Brian. He often played around in the woods, or chased pigs around the field. One day, however, he got lost in the forest. But he found a trail of glass blocks that led up to a house. Up by the house there was a person, who looked strangely like Brian. But still, despite the strangeness, Brian continued down the trail. Once he arrived, the midday sun in the sky quickly blinked to pitch-black nighttime in an instant. Brian suddenly felt tired, so he did not question this and wandered into the house to have a nap. The dream was very strange. He saw himself, his back turned from sight, watching a village below a mountain. Suddenly, thunder clapped. Then Brian's face zoomed into sight. It was mostly the same, with one small exception... His eyes glowed white. They suddenly pulsed brighter, and he waved his hand to the air, and lightning rained down upon the village, setting it aflame with no rain paired with it to put the fire out. All the dream went black after that. One sound remained... "Wake up..." Brian woke up the morning after as something not himself. With powerful abilities and a hatred for all things living, he realized what had happened. He was something different. His name was Herobrine. He opened the door of the cottage, and summoned creepers to destroy it, and asked them to build him a magnificent mansion by nightfall. And off he left, down the glass trail... And towards his doomed village.
