It might depend, a visual hallucination is a glitch/artefact in the visual processing center of your brain, a number of things can cause a glitch like this, in some cases stopping all input might infact stop the misprocessed stimuli but of course some hallucinations can be bought about by a lack of visual stimulation (Sensory deprivation ect) in which case you'd continue to experience the hallucination eyes open or shut.
on a more personal level only a minority of my hallucinations possess only visual elements, most are muti faceted, Tactile, Spacial positioning/motion, Auditory, aswell as visual, in those cases where I've stopped the visual feedback it often makes the other aspects of the hallucination more intense.
So once when sleep deprived I had a hallucination of falling forwards towards the end of the street, there was a visual element of tunnel vision and seeming falling. before I thought I was going to hit the wall at the end of the street I closed my eyes in addition to falling it then felt like I was tumbling and spinning out of control faster and faster until I opened my eyes again.
When experiencing sleep paralysis closing my eyes only exaggerated the sensation of begin strangled and pinned.
