Aphantasia is a condition where individuals lack the ability to visualize mental images. When they try to see images in their mind, they do not see anything, experiencing a blank or dark space instead. This condition varies in intensity among affected individuals, with some having no visual imagination at all, while others may have partial visualization abilities. Aphantasia can affect various aspects of life, such as memory, creativity, and problem-solving, and it can have different causes, including genetics, brain injury, or developmental factors.
