A bright steadily flashing light traveled across the dark sky then turned its direction toward me and hovered about 25' in front of me

Sitting about 14 feet from a large window looking through a thick mesquite grove to the dark northern sky a small (approximately 8" in diameter) bright light came into view from the west.  It was moving fast and flashing on and off.  When it was directly in front of me it changed directions and came down toward me straight through the trees with no sign of movement to avoid the trees or their branches. I was absolutely fascinated and with no fear. Within a minute or two I stood approaching the large window, cupped my hands around my eyes to get a better look into the dark night.  The light hovered directly over a low retainer wall separating the front lawn from the mesquite grove and continued its steady flashing. Suddenly apprehensive I started walking past a wall of windows toward the bedroom and watching as the light followed my path.  The bedroom drapes were closed so I carefully peaked through the opening only to find the light hovering outside the bedroom window.  While watching another few seconds it suddenly disappeared. I felt the light (or whatever it was) saw me sitting in the dark in the house and came to investigate or document my being on film.
Date may be approximate, although the witness does not indicate that fact.  PD
