I proved it to Myself by doing it, but until we invent BCI mind's-eye imaging, you're going to have to trust Me on the specific angle. That's one of the hard parts of the soulist scientific method: when belief is an independent variable in the observations, replication requires a lot of work. I can introduce you to other people who've done the work, and hope that our consensus persuades you, but I can't show the result to you with your own eyes. Your eyes are a scientific instrument, like a spectrometer or a microscope. No scientific instrument is well-designed for observing everything. You can't watch bacteria multiply with a seismograph.

More generally, I can prove the principles are valid. I can point out to you that babies don't know how to see yet. They haven't learned it. It's all just colours to them, they can't sort those colours into shapes and objects, that has to be learned. If it can be learned one way, it can be learned a different way.

I can also use analogy. When you go to the movies and see Indiana Jones disarming a trap, that's not real. It's just a screen with moving lights on it. But you don't see it that way, in that particular moment. You're absorbed into the story. You suspended your disbelief. You bought into the cues and it was enough to transform your perception. You didn't need a 3D image, you didn't need to smell the musty dungeon, you didn't need to feel the wind as the swinging axe went past Indie's face. What you saw was enough to choose to buy in. It is possible to reduce that threshold, so less stimulus is required for your buy-in.
