You are having palinopsia- abnormal persistence of image after it has been removed from sight.
It can have multiple causes, like a occipital epilepsy, multiple sclerosis, or migraine aura. As you said MRI Brain was normal, you may need a EEG, VEP, a csf analysis for oligoclonal band, and a review reporting of mri with different radiologist. In short, We need to evaluate for the cause of palinopsia and muscle twitchings, and treat according to cause.
