in my experience DMT is far beyond the bounds of LSD or Mushrooms.
I've dosed pretty high on all 3, but have only had 1 experience with combining a MAOI with an oral dose of DMT, and the effects were very subtle and barely noticeable. but from what i've read and been told, an oral dose of DMT done right, can be on the same level as a smoked dose of DMT albeit with a slower onset and much longer trip.
I've heard you can have an ego death with a large dose of acid, but i've never been able to go that far.... even with doses exceeding a 1000 mics.
When i say "far" i mean it like having an ego death, not knowing who you are or where you are. I wasn't afraid to smoke enough DMT to "breakthrough" but i needed to work my way up, and it took quite a few times to get to the stage where you go beyond the visuals and breakthrough into a complete outer body experience and ego death.
All the times before experiencing a DMT breakthrough, the impossible visuals, the seemingly alien yet non threatening entity's and the unique ways of communicating with them... to the huge body load transition of letting go and letting it take you on it's psychedelic roller-coaster.... all of those experiences have been nothing close to any other psychedelic i've had, nothing as vivid, nothing quite as spiritual... the onset and duration of smoked DMT doesn't factor, because i feel like so much more happens in that little space of time than a 10 hour LSD trip.
the closer to breaking through, the less sense of time one has anyway. When i finally managed to breakthrough, i knew i had achieved it the second i put the pipe down, and had just enough time to lay down on my bed. I didn't know where i was, and didn't know how i got there. I didn't realise that i'd just smoked DMT.... the only thought that my mind was capable of processing at that moment, was that i was dead. As i was completely detached from my body, which was running around on autopilot, I slowly started to hear music fade in(I almost always have music playing when i smoke DMT) and that was the first bit of reality i had to cling on to and made me realise what was happening. in hindsight i'm glad that i had something to hold on to, but always wonder how much deeper down the rabbit hole i could've gone.
Anyway, that was a while ago, but i remember it like it was yesterday.
