I would love to make a zine about lucid dreaming, but I am not 100% clear on how strict the theme of hypnosis is. I feel it's at the very least a close neighbour, but don't want to bomb the jam with unrelated rubbish.

Hi! It does need to relate to hypnosis somehow! If lucid dreaming for YOU connects to hypnosis, then that's great, but if it's JUST about dreaming then I would say it doesn't fit!
