Ok, so today I was fighting a zombie with a diamond sword and when I killed it, I went to retrieve the feathers when all of a sudden I started to lose 0.5 hearts per second. I quickly stepped out of the area and I stopped losing hearts. I went to retrieve the feathers again and it happened again. There were NO skeletons, No creepers, and NO spiders in the general area.
So at that moment, when I stepped into that general area I kept on losing hearts. I purposely killed my self to see if a "troll" message would pop up but it just said "You Died!" like always.
Has anyone else expirence this or did I just had a weird glitch or something?
(No, I'm not saying it is Herobrine. Stupid crap anyway)
