I had a recurring dream for years. It was kind of like yours. It was always in some house or building that was run down on a big piece of land and I seemed to be hiding out there or something and there was all this feeling of threat.
It wasn't animals though, it was people but no one specific. Anyway, I had that dream from time to time for years and it always left me feeling kind of shook.
One day I figured out what it meant. The personal details aren't important but the idea was I had terrible guilt about something, the way I had left something. I realized I had sort of underplayed it to myself, not admitted my part in it. I mean, one day it really hit me exactly which thing this dream was about, what the "place" represented and then everything made sense to me. It's hard to explain exactly. But it was very powerful.
It wasn't possible to do anything about it anymore, to fix it or apologise. All I could do was admit it to myself ask for forgiveness from the spirits and to forgive myself.
Anyway, since then, I have never had that dream again. Ever After having it for years.
So, be patient. If it's bothering you, it means something and if you keep working on it, you'll get an answer and then you'll be free of it.
I'm so grateful to that dream for what it made me learn.
