Welcome to the Nexus!
From your description, either your LSD was bunk or it was a very very low dose.
As for the DMT, I think from the way you describe, "I dont take the whole thing very seriously", I think this is a bad way to start and likely will end up at one point or another with you getting some very serious ass kicking from the experience. Please please read our
health and safety section! Unless I misunderstood you and you just mean that you dont think DMT is a doorway to another dimension, but whatever way you describe it, the experience can (and will, soon enough) change your life one way or another. Do check this thread regarding the interpretation to the DMT experience, it is one of my favorite ones:

Regarding your plan for caapi and mimosa, Im not sure if this alcohol soak will be so effective. It will probably pick up some alkaloids but possibly some will not have ben pulled. Also its always better to not just mash plant material but rather powderize it as fine as possible to increase surface area. Next time I suggest making a brew with them instead.
Another thing, the dosage seems off there. With mimosa an initial dosage should be around 3-5g, and with caapi, maybe 40g. This means if you take half of what you made, and if its been efficiently extracted, you would be taking the right amount of caapi and way too much mimosa/dmt... But potency specially in caapi can vary a lot, so for all these many reasons I think that plan is not a good one.
I highly suggest you first brewing caapi separately (check FAQ for instructions), and the mimosa separately. Start taking just the caapi the first time, around 40g. You want to find your ideal caapi dosage, so that you feel the caapi, have some tracers, a peculiar headspace, sensitivity to light, but not too much so that you have extreme difficulty walking and so on. Once you find that dosage, next time you take, you can take that dosage and add 3-5g mimosa to the brew.
Good luck, be careful!
