Cool/Imaginative/Vivid Dreams

Yesterday I had a nightmare. It felt like a film where I'm observing this girl devour the person beside them on the bed. I can't quite recall if it was a woman or a man. The girl is similar to a vampire or a version of it. These creatures are perfectly normal and live regular lives in society before they awaken. The conditions for them to awaken is to eat another person. It's like a sudden initiation of maturity. They might be ignorant or might be slightly/subconsciously aware that they're not human before it happens. The person they eat ends up morphing into a bat-like face, just like the face of the girl morphing into one in the process. The body corrodes and crumbles as they eat it, like it's sucking the vitality out of it. While i didn't see it in the dream, i just know that the corpse might turn into the same kind or just die in that state. The dream ends with the girl looking at me/spotting me. Anyway it was very unlike me to have that dream and I haven't had a horror one in a while; was also semi-lucid. Wasn't as terrifying of an experience but i do think it's kinda cool? As a manga premise or something. I've had some other dreams with cool plotlines too but share your cool dreams please
