Driving alongside a main road near a nuclear submarine station. driving then suddenly engine and radio turnoff really bright light and a whooshing noise. i was frozen and had a beam of light run from front to back of car. i felt it go through my body and could not move. all objects in the car were lit up - no shadows. everything in car was alight. as soon as beam moved through me i could move and saw it pass through the car. the engine then starts up it goes black in car and radio works. i looked for witnesses and a car came past shortly after i slowed thinking they would stop to check everything was ok but the car just passed as if it saw nothing. i could not understand how the car behind did not see it. i went home but didn't speak to anyone for about 3 hours as i was in shock.
