This will probably written off as a "personal vendetta post," but whatever, the contents of it are true...
You should know that the subjective experience of one individual is not any type of reliable evidence - it is certainly not replicable clinical data. I have one personal friend who has taken mushrooms with an MAOI, which altered the effects of mushrooms - but did not turn the trip into a replica of oral DMT - it was stronger, certainly, but dysphoric, and not visual in the same sense as DMT. I am almost 100% sure that there are others who have taken this combo without experiencing with the same certainty you have this replication of oral DMT. Search trip reports on the internet or even within bluelight and I'm sure you'll find some.
You can argue how certain you are, but in the end when there are conflicting reports of the same subjective nature as your own, there is no reason to believe your own are some sort of evidence.
You can say whatever you want, but I'm certainly not lying right now and given the plethora pharmacological reasons to believe oral DMT and mushrooms + MAOI are not exactly the same, even in effect... I think the best anyone can say is that taking mushrooms and an MAOI is very likely to produce a state that is extremely similar, or even the same for some people, as oral DMT.
