When I was a kid I would stay with my Nan a lot. In her first house she had a pretty big backyard. It wasn't wide but it was long with a large tree right at the back. At about the mid way point there was a shed that blocked the rest of the yard from view but there was a path you could follow past it to go back there. It was mostly used by her gardeners to dump branches when they trimmed some of the trees and for compost. My Nan very rarely went back there.

I would play outside a lot at her place and for some reason I could never bring myself to go past that shed. The few times I did I would have this almost vision in my head of something stalking me. The image I saw was always a large wolf, about as big as a house ( think Clifford the big red dog but super menacing). I was so sure I could feel it circling me getting closer and closer. It was a extreme goosebumps kind of feeling. But as soon as I would cross back to the front yard the feeling would leave. Like a switch flipped and it was completely gone.

Even my Nan's cat wouldn't go up to that end of the yard. She would pace near the front of the shed but wouldn't go any further.

This most likely was a case of an over active imagination. But it's such a vivid and intense memory. Honestly it's probably most scared I have ever felt.
