New Effect: Sulfur Hallucinations (False Entities)

I propose a new mechanic for the Sulfur gas. Instead of just Nausea, players exposed to high concentrations of sulfur should start seeing "Hallucinations". These are ghost-like images of Creepers or Zombies that appear for a few seconds and then vanish when hit or approached. Players might also see fake Diamond Ores. This would make the Sulfur Caves truly chaotic and unpredictable, challenging the player's sanity!
