1, i was sitting on my back patio facing south at 8;30pm, 2, i had a strong feeling to turn around. 3. i had no idea what the objects were but they varied in speed and pulsated in brightness 4. objects were flying partly in formation heading nw to ne. some seemed to merge as if to collide and then separate heading away from each other.5.i became excited and felt i was a witness to something that did not have a logical explanation. after the event was over i felt a surge of energy that lasted for over an hour. 6. the objects disappeared from my view over the tree line.
