I don't quite understand - was it that he had a dream in which he dreamt that he saw a computer image, or that he had a sense of recognition when he saw a computer image when he was awake, and he felt that he'd seen the image before in one of these dreams? Or what? (What I'm wondering is whether it's actually the dreams which are relevant, or something about how his mind is working when he's awake, which is more relevant to deja vu.)
