I can make it back to similar interesting states. I'm not sure if they are nonduality per se or something equivalent to it, but my personal model of felt experiences of my mind while meditating seems to find 5 or 6 layers behind the one I "pretend" runs everything cognitively on a daily basis, and that is just 5 or 6 qualitative equilibrium states where I end up and the ego or whatever is my awareness processor has a difficult time being there. This leads me to a more interesting cognitive model of my own awareness, where it seems like ego emotional responses are felt on the "top layer" but sometimes effect down the layers.
I've stopped trying to make it deep after half a week or so of trying to dive through every day. Its a weird added ego layer to the meditation that I feel like moves me from wanting to be in the moment and be here and be counting, to trying to be in a specific state that is percieved as "better" or "higher" or something like that. I.e. pushing on a results driven method instead of a process driven method, when the logic / value system behind me meditating was to be more mindful and have a better understanding of myself in different states and places (cognitive self understanding, especially as they relate to daily states and emotions). So I stopped trying and just focused on the practice. This is how I function the best and have the best discipline and results anyways (process driven over results driven). Meditation still tends to be a much more pleasant and fulfilling experience still after a week and a bit has passed now, and only _some_ of that should be attributed to the fact that I always meditate in the direct morning sunlight
