It sounds like there might be an individual sweet spot for harmala content of changa when smoked with mushrooms. It sounds to me that your changa was pretty harmala heavy, and the harmalas were heavily colouring the changa/mushroom experience...I think it would be worth making up another batch, while going easier on the harmalas and experimenting with that. Freebase DMT alone is also well worth trying in combination with mushrooms, I actually really like the combo of psychedelic + DMT, much less jarring and anxiety producing than vaping freebase from sober.

I would HIGHLY recommend any shroomy peeps consider experimenting with consuming fresh mushrooms, if they never have done so before. ALL of my most incredible mushroom experiences came through consuming fresh mushrooms, there is an extra sparkle or essence to the trip I don't seem to get when they are dried...your description of the experience being more rounded or solid resonates completely. Yes they are certainly more effort to eat, and yes they may be harder on the gut, but despite this, I still think fresh is best when it comes to mushrooms. I totally appreciate that peeps would much rather say chow down 5g of dried mushrooms compared to say 50g fresh Psilocybe cubensis mushrooms, but I would encourage peeps to seek out more potent species which I find induce a much higher order experience than P. cubensis as you need to consume a lot less to get to the equivalent place and it makes it much easier on the body. 10g fresh say of either Panaeolus cyanescens, Pan. cambodginiensis, P. semilanceata, P. cyanescens or P. mexicana is ample to induce a powerful experience.
