Chromesthesia and Epilepsy

This is my first post here but something happened last night that prompted me to seek answers immediately. I was wondering if anyone else here has any type of synesthesia or chromesthesia along with their epilepsy? I have severe epilepsy and have had seizures daily for a few years now. My seizures are worse when I'm very tired and last night I stayed up too late and experienced something very new and almost intriguing! With every sound/tone I heard I'd visualize it as geometric color or pattern. The colors were very specific to the tones and I can specifically remember which colors went with which tone even after I woke up this morning. Does anyone else here have experience with synesthesia or chromesthesia? Would love to hear other people's thoughts on it! Thanks in advance!
