For most, imagining an apple is automatic. For people with aphantasia, it’s like staring into mental darkness—no matter how hard they try, they can’t. 🌑
Their brains don’t light up like real vision. Their brain signals are flipped 🔄. This could explain why their imagery never reaches conscious awareness. But their brains are still building mental blueprints 🧠✨.
