As others have stated, I would proceed to a "breakthrough" level dose. For me, almost all of my scariest experiences have been when I have been caught in between this dimension and hyperspace. Once I have launched, I typically lose sense of time and fear.

Once you obtain a full breakthrough, you will understand the true power of this molecule. However, I wouldn't be surprised if you come back saying "Whoa, holy shit, that was the craziest experience of my life but..... wait, what happened?!?"

The speed, chaos, and intensity of the experience may still leave you wondering what you were supposed to pull from the journey. Over time, I learned to navigate, remember, and integrate a much higher % of the experience. As with anything, practice makes perfect!

Experimenting with different ROA's and dosages of harmalas will also help you tailor the experience to what allows you to learn the most.

Much love.
