Fear, hallucination?

For a few days I have been seeing a bright white light in the corner of my eye from my bed, but as soon as I look it is gone, in front of my bed is my PS4, when I sit there I can no longer see the white light, and as soon as I completely inside my eyes Close in the dark I see some eyes, which is why I always have the light on, does anyone know why?

I sometimes have. I think it's because my eyes relax in the dark and are then stressed too much when the lights are on.

Do you have any illness? Or it is just a fear that your body imagines

Thank you
