I suspect that they&#x27;re right for certain brains on certain types of LSD, but as someone who once had a pipeline to the stuff, there are many different formulations that produce dramatically different effects.<p>Distinctly, I remember watching Mars Attacks in theaters (which should date the experience) on what was promised to be a &quot;special&quot; blend... how it was special, I have no idea, but the visualizations were very unique.<p>In lieu of the strobe effect this article discusses, everything instead morphed.  When someone turned their head, for example, my eyes (brain?) saw their head briefly in both positions (with no gaps), and then they morphed from the first position into the second position, its path being trailed by a ghost of their heads.<p>It was unique, different, and I&#x27;ve never had another experience like it.  Perhaps there was something in the mix that wasn&#x27;t purely LSD, I honestly don&#x27;t know, but from my (admittedly naive) understanding, not every trip produces the same effects as every other.
