Bright Silent Light in the Sky Following Major Chord Played Across Entire Valley

At approximately 0315 of 27JAN2021 I was returning to my dwelling and was stopped from the source: perhaps A/C Units or other machinery in some odd sync. s I thought to say “no biggie,” just off to my right began, a somewhat louder and more. This sound played in a higher octave and forced me focus on this chord playing now as whole, in tandem. And No long longer had 5 minutes passed observing this, whan within 30 seconds a bright, thunderless crash lit up the night sky. The high pitch of an intake type of engine, bringing along with them an extra octave to the dual leveled hum that remained until the time I departed.
And, i departed at 3:47AM, immediately following some dashlights and AC going crazy.
