After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung

Continuity ties lightning to a waking moment of realization or a sudden, jolting event. It often follows news that landed fast. The dream may simply be replaying the shock of it.
Continuity hypothesis (our summary).Mythological
The thunderbolt was the weapon of the sky father, hurled by Zeus and forged for him in the deep. It marked divine anger, but also the spark of revelation. To be struck was to be singled out by the heavens.
