Does the goat mean anything? and if -what?

Can anyone tell me what the goat means in Pagan traditions? Had a dream, vision a while back and it was someone wearing a mask made of a real goat's face. Years back another symbol came up that I found when I had given up on searching what it could mean, and then it was the clothing, the "hats", of (male) members of Pagan way back in time (the only photo I have seen).

Anyone, please?
