So there are various meditation objects for developing concentration. The breath, a mantra, some form of visualization, and much more.

I have been using the breath, but I am starting to realize that I rarely ever notice my breath in my dreams so it's unlikely that breath meditation is conductive to lucidity until in much later stages where the meditation practice has increased my overall awareness and mental clarity. However, I would assume that advantage would come regardless of the meditation object as long as I continue to practice. So it would make sense to choose an object that would increase my chances of lucidity even in the earlier beginner stages.

Do you guys agree with this? I am leaning towards switching over to mantra meditation instead, but I am wondering if anyone uses another type of object such as visualization or a physical object or concept, and if they have had more success with it. I am reading the Tibetan Yogas of Dream and Sleep, and the author stated that it's ideal to use an object which is physical and external to our body. That would exclude mantras, but it seems like mantra should work out fairly well since we do think a lot in our dreams.
