The first couple hours there is disintegration. Anxiety begins to mount as perceptions loosen and unhinge from the habituated/conditioned way of thinking. The ego essentially is dissolving. We loose control of these conditioned ways of perceiving the world.
After the peak there is a few hours of this in and out of this state. It comes it waves as we try to make sense or embrace this disintegration.
After 6-8 hours begins the re-integration. Where we make sense of these new perceptions and experiences, and try to rationalize them, so they fit into resonant way of making sense of what happened to us. We create a narrative. We add structure to the otherwise unstructured experience.
The more lucy, the more disintegration and more ego death. Which can be extremely frightening or liberating depending on your mental state.
I think it should be respected. It’s powerful. It changes you. So it shouldn’t be used recklessly. It should be a tool for introspection.
That’s why I usually do or recommend 1/2 to 2.
Anything more is really unnecessary. Unless you really really really want to see how far the mind can bend, and snap back into shape.
I really appreciate how it has an amazing ability to decondition these unconscious biases, these habits that trap us, confine us, limit our imaginative ability to perceiving the endless possibilities that exist every moment before us.
