I don't think that closing your eyes automatically means you're imagining a performance. I find that the visual information gathered by keeping eyes open can sometimes be a source of distraction to the music. When I close my eyes, the only thing I "see" are the sounds (better visualisation of every note, NOT a scenery with people playing music).
That being said, I like to keep my eyes open too. Either to enjoy the very warm and dim light of my bedside lamp, or to avoid falling asleep.
