This is my understanding. It's also what I argued in a thread about Mr. Robot (a show where the protagonist perceives an individual who doesn't exist) sometime back. Someone was asking how Elliot could be on a computer while Mr. Robot is scanning a bookshelf. My proposal was that Elliot memorized the bookshelf as he walked past it.
