Triangular object blinking. Smaller objects moving either towards or away from main object. Part of triangular object would blink then the smaller one(s) would blink the same color. Seemed to be moving upwards away from where we were standing. At one point, one smaller object seemed to be swaying towards then away from larger, triangular object. Faint whistling was heard from all directions along with pings coming from the general direction of the object. One small object moved above the house (another one disappeared behind a neighbors). Observed a few streaks heading in the direction of the triangular object. May have been meteors though. Before going outside, a flash of light came through a window. My friend and I observed the objects until we suddenly felt incredibly uneasy for no reason.
