Minecraft ghosts?

Hey guy's this really did happen to me so please dont think im lying.

I was just making a slime farm on the 7 level and then when i was making it 2 zombies came out of nowhere so i killed them then more came so i lighted up the area then when i was done with my slime farm i turned around and then i saw some block's missing and some torches so i was worryed and i couldnt find the torches that was lost and i looked everwhere!

So guy i was wondering did they really deleted herobrine...

Tell me what you think about this and tell me did this ever happen to you.
