Flashing sky, bulb behind clouds. TRUMAN SHOW SUN.

The artifical sun is behind clouds, look to see it flashing.

Watch the Truman Show and watch one of the bulbs falls from the sky.

Reseach Telegraphing (entertainment). It is when creative works are produced to convey clues to the audience. The Truman Show, where clues about your reality can be had.

God bless you all.
