You are describing subjective experiences. We can all agree that subjective experiences exist and they may have psychological value, and even health benefits (stress reduction, psychosomatic reactions, placebo response). To extend this to a method of explicitly physiologically-targeted treatment underpinned by a nonsensical, non-scientific biological framework, however, is where the quackery enters the picture. To give an example: Treating stress by teaching a person meditation is a rational course of action because we know that meditation affects neurological processes in the brain. Teaching meditation by saying (I'm making this up) it unclogs ghosts in your energy field is quackery because it offers a nonsensical explanation as well as hinges on metaphysical phenomena that cannot be tested nor disproven because the terms (ghosts, energy field) involved are not physical.
