Within the dreamscape, try to focus and the feeling they gave me. About what I felt when I fought them. Living Nightmares are just beings created through fear. Their mind forms from thoughts of fear. Their body, from belief in fear.
So what I should be using to find them, is fear. Fear, gives off a smell. Perhaps I can utilize that. I have plenty of ima to try out different things.
However, one idea came to mind. As I had once gone into a dream of a little girl. Her dream was her being led around in a forest of glowing flowers at night. She was being led around by a glowing moth. The entire dream was just her frolicking around while being led by the moth.
That moth will also be my guide. I did not want it to die to a Living Nightmare though. I needed to give it a way to protect itself. I knew what to give it.
