At personal storage facility, getting some fresh air and...

At approx 19:44hrs I had stepped outside the storage facility I have storage at for some fresh air and not doing anything specific and flash! stutter...stutter...stutter...flash! fade to black, yet there's like this dark very dark blue-ish/brown coloured cloud barely barely visible IMO that its hiding and dancing around in, the flash deformed or morphed? into a spark! now & I can barely see the spark! now, flash! (like seeing fluffy broken cloud cover and this object is 'presenting' itself as, for whatever reason) is done and that spark! is now fading, fading fading as it 'flits!' here, 'flits!' there. Like a peek-a-boo! game, from up high. *Points upwards. Not too high an altitude, not typical high altitude trucking along craft(s) or objects IMO. Maybe 10,000 to 15,000ft. in altitude. Until not viewable from my line of sight looking to the S-SW at the storage facility... outta nowhere blamo! that odd cloud like formation (mostly coloured dark brown, dark blue against mostly black/dark sky) dwindled and faded away as well. Something was either up there and BIG maybe supporting those craft/spark! objects?
In closing, for whatever its worth. The immediate (1st) and only impressions I took in on the cloudlike formation *see artistic representation here . The 'light' or craft direction of travel depicted in drawing would go clockwise. Meaning. At top of drawing follow 'light' object clockwise until it is barely visible on far, upper left of artistic representation... make sense?
