I was wondering what peoples experiences were with some of the non-visual hallucinogens.  DMT is probably the most visual hallucinogen known whereas other hallucinogens like 5-MeO-DMT, MIPT, and AMT are commonly reported to be devoid or have only minimal visual effects.  They are still classified as hallucinogens because the do induce the characteristic mental and emotional responses.  What other compounds have people used that lack visuals?  Or taking these compounds with medicines like SSRIs that decrease the visual effects?  Thanks.
