Whether it was an altered state or not, it showed me the ability to see vivid imagery. And the experience isn't even on the high end of reported abilities to visualise.
Yea and it seems weird to assume that since these states are possible that most humans are mistaken when for millennia they’ve talked about having mental imagery. The idea that aphantasia is just language confusion is so strange to me. As someone who has aphantasia I understand the “oh shit” moment when you realize that there’s more going on but the evidence seems pretty overwhelming to me that most people have some internal imagery.
That almost all our language about recalling physical objects talk in terms related to images in retrospect should've been a dead giveaway, and I do remember many instances growing up I found it weird, because it seemed like dumb ways of talking about things you couldn't see...
It's to the point as we see it's hard to even talk about recall without recalling such words - e.g. "imagination" itself presumes images.
