Hi Brandy,
Unfortunately I don't know much about these horse ties or the locations you might find them, but the fact that you have this dream often could mean it is past life related.
I've never had any recurring dreams myself, but I find that some elements do repeat themself. For example, I often had dreams of the Red Square in Moskau, Russia. Sometimes I'd be at a ceremony, other times I was a tourist, and once I was there for Lenin's funeral. Later I realised I had travelled there often in two different lifetimes. I think, if you keep seeing this stone corridor, it must hold some significance to your past life, because why else would you remember it so well? Could you have been a stable hand, or just passed through the corridor often, or did something important take place here?
Perhaps you could try writing down as many details as you can, then try to do some research on possible locations or time periods. A good start, if you remember the appearance of the corridor, would be to look into architectural styles throughout history (e.g. the Tudor arch is quite striking, or maybe it was something more gothic-looking). The quality of construction would also be quite telling - a castle or church corridor would be better built than a commoner's house or village inn for instance. I saw your other thread where you mentioned feeling a strong connection with the Tudor period. Perhaps this dream has something to do with that era.
What happened in the dream? What were you doing? Do you remember what you were wearing, or if there were any other people? What sort of building is the stone corridor in, was it in a basement or castle or small house? What was the lighting like? Any windows? Were the walls damp because it was raining and the water came in, or because it was cold and there was condensation?
Just some questions for you to think about, that might help with identifying the location or time. Something I like to do is to write all my thoughts on a text document alongside a picture that triggers memories. That way, I can see all my research in one place.
Best of luck,
Spiegel.
