There is a condition called aphantasia, iirc, which prevents some people from being able to use visual imagination.
To get a proper answer to your question, imo, it would be best to try to research the scientific literature for a general answer or, better yet, to consult with an expert in neurology about your particular case.
That said, if the real problem is just an underdeveloped, or weak, visual imagination–or (perhaps) a bit of tangled wiring–you might benefit from exercise and plasticity.
I do believe that mnemonics practice can help strengthen an underdeveloped or weak visual memory, but I would be sceptical of anybody who does not have a strong professional background in neurology who purports to have a sure solution.
My apologies if I have not answered your question in a satisfying way. My real message is just to say, beware of answers from enthusiastic people who want to help do not have an in-depth understanding of the conditions that can affect the brain.
