hearing sounds from watching gifs/looped videos

i want to know of anyone else with sound-to-color/shape synesthesia also experiences it backwards! i noticed the other day, when i watch a gif or a video on loop, i start hearing sounds while seeing the motion/colors. they are usually very faint scraping noises. does anyone else have this?

i have chromesthesia and grapheme-color synesthesia. let me know if anyone else experiences this :) i was trying to explain it to my husband and he said it sounds scary lol. it doesn’t feel scary at all, just like some synesthesia quirk
