What causes phosphenes when waking up?
I'm curious about something. Do you know what causes phosphenes when waking up?
Yes, I can definitely help with that. Phosphenes are believed to occur when light-sensitive cells in the retina are stimulated by pressure or movement. When we rub our eyes or even when we move our eyes rapidly during sleep, the stimulation can create visual perceptions without any external light sources.
