Any good interpretation of dream must begin with the psychoanalytical rendering of the manifest dream symbols in relation to classical mythological contexts and reach a valid correspondence between that and the context of the dreamer's life experience in order to identify the latent content of the dream and thereby decode it's meaning. I'm assuming that you are a man, as this is posted in the men's dream section, so this will help the analysis. The fact that you are climbing a mountain and that you come to a great house at the top can be described as your upward journey toward the pinnacle of achievement. As referenced in the link, "the goat, which climbs the highest peaks and possesses wonderful vision,...sees all, past, present and future". Perhaps you are seeking something coveted, and your climbing in the dream symbolizes your desires. The large house at the top, a symbol of possessing that which you covet most. What happens next? You are accosted by a virile he-goat whose energy cannot be contained by the weak fence, and this may in fact point at a realization psychologically that your libido, sensuality, masculine virility and energy stand in opposition to aim of your desire. You go at one moment from being just a few steps away from a mansion to being forced into an outhouse to avoid the violence of the goat, which very well may symbolize your own sexuality. It's a telling dream, if you buy this interpretation. I'd be curious to know the context of your life experience at the time of this dream.
