(Closed Eye) Flashes of light

Hey everyone, does anyone else experience this weird thing when they close their eyes? Seeing flashing lights? Sometimes they’re super bright, like looking at the sun through a glass window, other times they’re subtle but still noticeable. This has been happening to me every single night for the past 6 years.

Sometimes it’s not just flashing lights, sometimes it’s like a fast strobe, other times a huge bright source brightens my closed eye lids, or even the brief flash of specific images from my trauma. I’ve talked to mental health professionals, and they’re just as puzzled as I am.
