V shaped silent craft with 3 red lights on each point.

A V shaped craft with 3 red lights on each point, flew silently from the North West going in a South Eastern direction.  I watched it for approximately 30 seconds before losing sight of it behind a group of trees.  We are  well acquainted with the sights and sounds of many types of aircraft coming in and out of  the nearby (retired) Castle AFB. This was not at all like any of the usual aircraft in the area.  The altitude was that of a small plane, but it was completely silent.  Immediately after observing this craft I experienced a physical reaction of anxiety, lightheaded dizziness and shortness of breath.
