Luminious bird like objects crossing the sky.

I was sitting in my hot tub and noticed a chevron/bird like illumanted object moving across the sky.  It was travelling at great speed and moved south to north in the clear evening sky with no sound.  There were three sighting in total.  The first consisted of 5 bird like illumanions almost ghost like in a triangular form.  In the second viewing there were only 2 visible moving north to south across the stary sky.  Then finally two of these ghostly bird boomerang shapes crossed again and then faded off towards the east.  
I was Not drinking and do not use drugs!
