Your point about sorting this out is a good one, given that it is not always easy. Definitely not all psychedelic experiences include the A&P, but some definitely do, as plenty here will attest, and teasing that out is complex and could benefit from more research dollars from people who know science, that territory, and the insight maps well, which obviously is a hard combination of things to have align often.
I feel it's important to recall that the map layed out by the Visuddhimagga regards knowledges of formations; insight into the nature of experience.
People have weird energetic sensations. People get depressed. These are normal human things.
If we have some "A&P phenomena" but we remain lost in content and identified with our experience, then there is nothing gained, nothing known, and nothing purified. If there is no insight into the nature of reality, then what has been attained? Where does the wisdom come?
This tendency to build conceptual mountains out of every blip and twitch is a failure to recognize the nature of wisdom.
