What causes a person to see red flashes very quick when having a seizure?

During a seizure, abnormal electrical activity in the brain can disrupt normal visual processing, leading to various sensory experiences, including seeing flashes of light. These visual disturbances may occur due to overstimulation of the visual cortex or disruptions in neural communication. The "red flashes" could be a result of this altered state, where the brain misinterprets signals, causing the perception of light even in the absence of actual visual stimuli.
