Hadde du overnattet på et hjemsøkt hotell?

Poster den jeg, så får de som gidder lese 😀

I'm from Norway so please excuse my english, I'd like to share my story and I'll do my best to write understandably. 😉
This happened a few years back on a field right by our house. It's early morning and I'm walking two of our dogs, retrievers - happy, outgoing dogs, not afraid of anything. They are running free in front of me, sniffing around.
Suddenly I see this large figure - maybe two meters tall or more, I can't really describe how it looks, it's kind of shadowy, greyish and the whole figure is... trembling, in a way. It's not a person. It's maybe ten meters or a little less in front of me. I get SO SCARED, it's a feeling I've never had before - I can't really describe it. It's moving towards me.
The dogs see it at the same time as me, one of them first barking fiercely and then they both turn and run home as I've never seen them running. I run too, oh my we ran. Nothing more happened but I felt scared for hours - the feeling kind of stuck with me. I didn't walk there for a long time.
It never happened again but I've been thinking about it a lot. What was this?? I mean, if it had been an animal of some sorts the dog would've chased it, I've NEVER seen the dogs act scared, not before and not after this. And they have never run home, away from me on a walk.
Well, it feels good to have written it down, I don't just go around sharing this with people.
Ideas to what it could've been?
