I have experienced something similar, namely hypnagogic hallucinations, usually when waking up, that sound exactly note for note the same as the recordings. Strawberry Fields Forever was the most memorable. To my mind experiences like this and particularly vivid dreams show that our mental capacity for self-stimulating is profoundly more extensive than most people believe. I can't think of any reason why you couldn't have a kind of state of lucid wakefulness effectively functioning as an overlay of what your sense organs are telling you. Imagine for example a race car driver who sees the line as clearly as in one of the simulation games that enables it. Edit: I've also had vivid hypnagogic visual hallucinations intentionally. It's a kind of fun game to play, seeing my bedroom clearly with my eyes closed, or checking the time on my watch while same. Obviously I'm conscious and aware that I'm not really checking the actual time, but not particularly surprisingly I'm pretty close since I tend to wake about the same time every day.
