What is this symbol? demonologists and/or psychic help please?

I saw it months back. It appeared in my dream. It was just a black symbol on a white slate. The symbol looked like an upside-down trident or pitch-fork with little cuffs or arches at the end of each spike. The arches were facing out. What is this? I'd like to know more about it. Also, a black shadowy figure follows me from afar. I dont physically see it, but I know it's there and know what it looks like. Black smoke hindering around it as well. Possible ram horns & pretty tall too. Not coming close, but at a distance. Tell me? Serious help please. I just wanna know more on both of these.
