On the day May 18th 2012 i was strolling through the forest in TEF... suddenly i saw a deer that looked like the zombie deer on halloween... but the deer was standing on the bridge near the pond and he was transparent.... you could slightly see through it. His pictogram was just like mine.. but later on it changed.. he never moved his spot he only scratched his neck and stuff like that. i casted spells on him but nothing happend. But when i exited TEF he wasn't there. Other deers didnt seem to notice him.. What is happening?

INFO ABOUT HOW HE LOOKED LIKE:
He had a grey skin with red scars on his body, and you could see blood and guts and bones.
He had a skull mask
He had the Huge red fan horns
