systematicity, ontologies, phenomenological and otherwise:

If only one could make a list of what needs to be attended to, and then one could just go through the list. Unfortunately, people’s ontology and ordering for what’s good to do when will be idiosyncratic and complex and evolving and ultimately (often) very fine-grain

But, it does matter what you do when, and that’s part of wayfinding. But, when you just don’t know what to do, you can be systematically experimental. This helps at least somewhat to keep from systematically leaving something out.

• inner senses (inner/imagined audition, visual phenomena, talking/thinking
• in between senses (phosphene splotches behind eyes, harmless tinnitus-like tones)
• outer senses
• valence/feel
• chakra-esque: crown/scalp, brow/face, throat/jaw, back-base of skull, back of neck, heart, solar plexus, naval, dan tien, genitals, sacrum, coccyx, perineum (for the mediate ones, both front and back of the body)
• meaning, nonsymbolic and liminally verbal knowing
• slightly-out-of-phase-with-normal-attention-"inner space" that is both seemingly "in there" and in-there-"out there" or "out there"-in-there...
• non-euclidean body-related space and "inner" space
• other "non-sensory" or "non-traditionally-sensory" phenomenology
• stuff/things/experience that is "out there in the world" but somehow not directly sensory, in character
• "body" or "mind" that’s somehow "outside" the skin or "somewhere else"
• skeletal muscles (every last one of them)
• interoception (visceral organs, sinuses of the skull, pressure, heartbeat, peristalisis, autonomic arousal, etc.)
• dermatomes (tiny random patches of skin/sensation all over, matter)
• somatically-overlaid-energy-full-body-movement-anticipation-planning-space, "energy work" space, phantom/ghost/energy hands space, "inner stance" space
• different frequencies/periodicities (Hz/milliseconds/half-seconds/seconds) of sensation at different depths of the body from skin to bones and inside the bones all over [buzz, tick, waggle, flickering, strobe, vibrate, tickle, wiggle, undulate, writhe, bounce]
• extremes: crown, perineum, hands, fingers, fingertips, sides of the fingers, wrists, ankles, palms, toes, soles of the feet
• edges: backs/fronts/sides of the arms, backs/fronts/sides of the legs
• creases: jaw/neck...
• boundaries: back-base of the skull...
• vestibular sense: phantom/immersive/vertigo-like moving, translation, spinning, going upside down, rotating
• ki, qi, chi, ruach, prana, energy...
• the "voluntariness of breathing" (versus the "involuntariness")

Sometimes you might experimentally want to increase the rate and depth of breathing, if breathing has become too subtle to offer certain kinds of systemic feedback.

also: the subtle movements of your eyes, the subtle movements of muscles in the back of your head and neck, subtle movements of the tongue and jaw, glottis, lips, palate.

states can be important too: sexually aroused, not sexually aroused, desirous of sex, not desirous of sex, possibly various states of emotional arousal

Finally, here are some ways that people systematically leave things out; as best you can make sure to not be systematically avoiding anything, of course with fast moving mind (belief/expectation/thought/imagination/feared possible truths and outcomes, etc.) and sensation stuff, but also old injuries, unsettling or unpleasant sensations around permanent pins or staples from old surgeries, scars (injury or cosmetic), genital circumcision, feared body stuff (cancer? precancer? did i fuck up nerve/ligament/tendon permanently? etc), phantom or feared teeth and jaw stuff, unpleasant "wrong, nervy" stuff. or maybe you don’t like your hands or feet or stomach or thighs or something. don’t avoid.
