For me, harmalas, in basically any dose, really shine when combined with other things like tryptamines, cannabis, and melatonin.
But several really interesting things begin to happen at high doses, especially in silent darkness. Some is virtually impossible to describe since it's the architecture of thought/awareness itself that shifts. The tracers are just the beginning. Thoughts unbraid in the dream trance into many avenues simultaneously, maybe to how a savant must perceive a vast field of data whereas most of the time we normal folk are zoned into a more linear awareness. Awareness can naturally blossom intricately evolving idea complexes. When entering the sedating visionary trance it's common to snap out of it the moment you realize you're experiencing/seeing something indescribable, then it will fade. It gets easier to stay in over time.
Like with regular ayahuasca type brews with DMT, it can get fairly Pablo Amaringo esque. It makes complete sense to me now that Caapi has been referred to as "The Force" with chacruna being "The Light". Or caapi being the cave, with chacruna being the torch that lights it all up.
Things can begin to seamlessly shift from being almost "imagined" or day dreamed about (i.e. thoughts, sounds, scenes, sensations), into actually being experienced as if it was happening.
This isn't that surprising when considering the brain imaging study on ayahuasca that found that people who visualized things while on the brew had brain activity similar to that if they were actually seeing it. Still, this doesn't explain what "it" is. My feeling is frequently that imagination/consciousness seems non-local in nature. When the veil lifts it's as if the core of the imagination/consciousness is further revealed, and some of these ones remind me of the 'object' Terence must have been talking about. And some kind of carry away of increasingly expansive visual perception and thought into sober life has been fascinating.
With harmalas it can be almost like a field or collective unconscious that is tapped into, and any place/person/thing/imagining could be experienced. Funny enough when walking around these 'places' I tend to be very harmala'd, and sometimes have difficulty walking.
Anyways, the nausea at the doses that bring in more classical type OBEs can be heavy, but when laying down still in the dark you can find the sweet spot and it gets easier over time. The out of body experiences come during the trances, in many different ways. But all with that 0 gravity feeling that's probably more similar to what people mean when they say 'astral projection' than hyperspace, most of the time. On a caapi trance, I've had what seemed like a type of orb or ufo approach, and pull me out of my body in a beautiful jungle green light that was very euphoric. Or just hopping a stair railing in the trance space, with that moment of mid-air 0 gravity triggering it. A lot of strange scenarios in the trances have triggered OBEs for me where I'm floating around the room spinning. It can be fairly confusing and nauseating at times.
Long story short I think they're vastly underrated and play well with others
