I think legit MDMA hallucinations are from when you're getting a good amount of brain damage in some way. Some serotonin receptor damage maby...
Was your monkey in or out pressed? Out pressed were pipes... in pressed were dank apparently, they may have had some meth, which helps you get on your way to this stage you've mentioned.
I think that being deep in the dirty euphoria late in a day that started out with mdma/meth/2c-x pills(too many), and was followed by more drugs and more of those pills, where everything is glowing, especially green things, and everybody around is somebody you know(not really, but they look like it, and they stare at you when you say hi to what you think if your friend). The ground is flowing while you walk with it. Sometimes I felt like shit though(fixed with more drugs), should have remembered tyrosine!
Is the ultimate form of your own trippy world fucked up insanity look that I've been in, because it's more real seeming then things like mushrooms to me. I still need to do K though..
