Personally, I did a whole lot of acid in the 1970s - I remember visual distortions but have no idea whether or not they were images b/c when I am not high on acid, I can't recall my hallucinations

I've been reaching out to friends and relatives trying to figure that out myself. I too have extremely vivid dreams but forget about it when I'm awake, maybe if I'm falling asleep or in moments where I get super distracted and drift out of existence I get like a 100ms flash of something like a dream but that is it. Everyone I talked to said that their visualization is at some spectrum of the visualization in a dream. One friend actually put a number on it and said it was like 60% of a dream because the immersion was not there as he knew it was not real. I can't know how they visualize, but based on what I've asked and have been told by all of them that it is to some degree like the visualization in dreaming. As I can visualize vividly in dreams I can confidently say I cannot remotely summon any feeling or visualization that is like a dream of my own volition.

Idk what people without aphantasia can do, but you 100% have aphantasia.
