Ghast Attack In Peaceful Mode

Ghast attack in peaceful mode

Survival, peaceful mode, on the nether
Before I heard the sound of ghast in peaceful mode, I don't think ghast will attack. But the sound of the ghast like when ghast will attack the player. I don't really think about that because it's in peaceful mode. A few moments later Fireball came to me and blew up the area. I died because of that.
