My ex was an IEI and she has dyscalculia which makes it difficult to perceive time on a number line or anything related to mathematical distances in space or time, so Ni doesn't necessarily imply good sense of time. She could plan the long range future sure, but not keep track of time as a concrete number or even intuitively.

And being Autistic also makes it very confusing to decipher metaphors and abstract language, which probably has some effect on how my creative writing skills are expressed. For this reason, I have a love hate relationship with poetry- "God damn this makes no fucking sense, but god damn it sounds so beautiful!"
