&gt; Without a doubt<p>That&#x27;s a claim that can&#x27;t be substantiated; there is in fact nothing but doubt since there&#x27;s no evidence to lead to the conclusion that hallucinations in your mind have any connection to the outside world.<p>&gt;  accepting the accounts from those participating &quot;as if&quot; true and then working backwards systematically towards a theory or direction.<p>No, that isn&#x27;t how science works; that&#x27;s religion.  Science doesn&#x27;t accept claims as if they&#x27;re true without evidence they are.<p>&gt; I cannot emphasize enough, what you encounter in the DMT or Aya state can be totally alien and extradimensional, and the themes you find within seem to be consistent across highly disparate cultures as well as time.<p>Because it&#x27;s a drug that affects humans the same way and gives you hallucinations and ego death; not because it in any way connects to extra dimensional reality.
