Perhaps you've already discussed it before but I'm a new comer...anyway my question is, can they appear in dreams? A few years ago, a strange creature haunted my dreams and my mother's. We saw the exact same creature! We were sick of that so I told my mother: "I'll take care of it!". So the last time that creature came into my dream, I chassed it and yelled: "Get the h**l out of our dreams and leave us alone!". It was scared and went away. Never came back in our dreams again!

Sounds more like succubus/incubus

Maybe we should Sìdhe, I posted it here because the creature was kinda shadowy, I could not see his features! But it had horns... I'll say like DV...
