Thanks for writing that up, your words are very vivid and I feel you on the dichotomy of DMT - sometimes so healing and friendly, sometimes dark and frightening. I have a friend who described a trip very similar to your later one, where when she went into DMT space she heard a voice triumphantly exclaiming, "we have you now!" and ever since she's felt uncomfortable about doing DMT. I've also had some experiences where I felt some kind of possession might be going on... weird and disconcerting to say the least!

I'm sure if you have migraines you've tried all kinds of things, but have you tried feverfew? You have to take it regularly (about a month to start working) but after that it reduces the frequency and intensity of migraines for many people. Tanacetum parthenium, it's pretty easy to find, even grow your own. The best time to harvest is late in fall, after a few good frosts.
