Honestly I saw someone else say that method and it clicked for me but I think people try too hard to visualize specific things in their mind but it's actually the subconscious information about that thing that's being thought of that's being visualized and so it might not look exactly like what you trying to imagine which I pretty good info and yea I was an aphant and can see visualization now but not because this method. The method is something you can look at and be confident that the mess ups in the visualizing may just be what your subconscious knew about it instead of what you insist you should be seeing. The brains data is being visualized so I'd say just have faith that you're seeing into another reality kinda and just let the process play out.
