Anyone else find it easier to visualise with their eyes open?

When I visualise with my eyes closed, the background is difficult to discern and the scene doesn't feel totally realistic. But when I visualise with my eyes open, it's like augmented reality (like the Pokemon Go game), where I superimpose the image of the specific person near me upon my surrounding environment, as if she is really there.

If I can't visualise with my eyes closed, is it ok to visualise with my eyes open?
