Dream Yoga

Does anybody have any experience with this practice? I'm not actually part of any Vajrayana lineage, more of a Zen guy, so I dont have anybody to ask irl. But I'm very interested in this one practice. I'm starting to have some luck getting lucid in luminal states, like with a light nap, but not in deep sleep. I've been told to start a dream journal, but I am just soo not a morning person and haven't developed the discipline for that yet. Any other methods, suggestions? Thanks!
