Ghost monster and hallucination effect

Hey Minecraft The ghost is a New monster Idea that i had that i think It would be a spooky adition to Minecraft. Heres how it works: This monster would be Very comun in caves, when he is far away, he becomes totaly invisible, but The closer it gets to you, the more visible it becomes. He can't take damage when you hit him, but he has a weakness: torches. When you put a torch near him, he starts taking damage until he's defeated.And if you place a flashlight, it takes more damage, so whenever you're in a cave, place torches to scare away the ghosts, but if you don't place a torch, He will find you, but he won't harm you; in fact, when he touches you, he will disappear, and you will start hearing laughter, and you will also have hallucinations. There are 3 levels of hallucination; in hallucination 1, you only hear mob noises, usually mobs that don't appear in the biome you're in.In hallucination 2, you start seeing messages in the chat, but not from other players; it's just a hallucination.And at the last level of hallucination, you'll see hostile mobs; they don't move, but if you get close or wait, they'll quickly disappear, and this can be very confusing at night, Because while you see stationary mobs, you also see mobs that are chasing you, and this can end up confusing your attention and vision a bit.Oh, and one detail The hallucination only levels up when another ghost possesses you; 1 ghost = hallucination 1, + 1 ghost = hallucination 2 and you get it
