l have a feeling that l had some form of this when younger due to trauma. but later in life l became very good at mentally visualising almost anything l wanted to imagine. But wife might be like this because she can't or rather she has difficulty visualising how to get to a place we had been to many times. She also flis out if l try to describe a location in our yard where something is to be found, such as a plant growing.because she doesnt appear to visulise the verbal descriptionlas andimage. l did ask her if she could imagine holding a cube in her hand that had different colourcolours for each side, and turning it over slowly to look at each colour and she said yes she could. l think the idea of being able to visualise a colour or rainbow is wonderful because it relies on what you seen and long term memory. it may be cured with practice or stimulation of the visual cortex.
