In my dream I was running and hiding from a large werewolf and I could feel his energy as he ran right by me but when he finally found me instead of killing me like I thought he would I turned into a wolf too and we ran together until I finally woke up
Are you sure it was a werewolf and not just a spirit-wolf?
I could see it being maybe your totem animal, or maybe its your "guardian" animal.
I hope this helps!
