For myself, visualizing isn&#x27;t exactly &#x27;seeing&#x27;. It&#x27;s just  sight-like, in that the same general information about shape, color, arrangement, etc. can be pulled up, with effort. Closing the eyes isn&#x27;t strictly necessary, but helps avoid the distraction of actual sight.<p>It&#x27;s very sensitive to attention&#x2F;intention: asked to visualize a person, I&#x27;ll mostly imagine the face and general build – not even picking specific clothes – unless that person is very associated with some outfit. But if I think more about some specific prompt – say, &quot;what were they wearing at some recent event&quot;, or &quot;think about their hairline&quot; – I can call up (or pick) reasonable details.<p>I suppose you could say it&#x27;s no more vivid than it needs to be, and with concentration it becomes more vivid&#x2F;detailed, but never quite like the solidity of a photograph.  (Well, maybe while deeply concentrating with eyes closed, or half-asleep, or actually dreaming, there can be moments of seeming realism...)
