I did a 200mg harmine versus 200mg harmaline bio-assay recently - minimal feedback from the harmine but the harmaline put me on my back for several hours with nausea and dizziness.
I can relate.

I once had some caapi so strong in harmaline I could only get to the bathroom by crawling, but I did manage to close my eyes for a period of 10 minutes, and saw scenes from medieval period, beautiful gardens, ships traveling the ocean, all in monochrome green, like looking at the reflection of images on a turned off tv....highly detailed images, like dreaming while awake, but these were not things I ever saw in nightime dreams, they were caapi visions, completely unrelated to night dreams.
Approaching a couple hundred mg of tetrahydroharmine can result in fantastic visions in dreams, similar to brew amounts below.
2005: Brew below is 100ml or 3.3oz, simply multiply each figure x 100 to get the mg amount, examples:
entry #1 from UDV is 183mg tetrahydroharmine, 9mg harmaline, 172mg harmine.
entry #22 from Santo Daime is 168mg tetrahydroharmine, 0mg harmaline, 198mg harmine.
entry #29 from Shuar Indian is 163mg tetrahydroharmine, 0mg harmaline, 180mg harmine.

A traditional saying among Ayahuasqueros is that the jungle vine brings powerful realistic visions, but that the chacruna brings light to these visions. According to the view of Western research, this is not the case; essentially the entire psycho-activity resides with the chacruna leaves DMT content.
Ayahuasca researcher Luis Eduardo Luna recently observed that when surveying tribal lore praising the jungle vine, he could find no traces of similar mythology around the two most common plant admixtures; psychotria viridis or diplpterys cabrerana, even though these DMT plants to a Westerner would appear much more important than the harmala alkaloids of the B. caapi liana.
Bottom painting: what a typical traditional Ayahuasca vision looks like when you combine large amounts of the teaching Caapi with psychotria to light up and color the visions. I have seen the beautiful naked women before like in the painting, they were spinning in front of slowly rotating marble pillars, breathtaking visions similar to what Amaringo painted.
