Thick white bar of light descends while moving left to right in my field of vision. Flashes and disappears four times as it descends.

So last night, about 3am I was sitting up in bed, looking out the window...and I saw a weird white bar of light with a faint blue aura that made four intermittent flashes as it decreased in altitude with each flash - but staying horizontal as it moved across my field of sight. As best I could tell it was three or four hundred feet from my house, across the street in the woods. The white bar of light was probably about 8-10 feet long. We were having a lot of heat lightning, but it was not raining and this was definitely not lightning. It was a white bar of light that flashed, then disappeared and when I would see it again, the bar of light was a little lower and more to the right, It did this four times that I could see. It was very quick...the four flashes happened like: light, light, light, light (the entire episode lasting 6 to 8 seconds in total I would guess). I continued watching in the region where it looked as if it was headed to for about half an hour, and I saw many slender white streaks of light shining up into the sky. This was not lightning...the streaks were more like one of those beams they would put infront of movie premiers long ago...but the streams of light were much thinner. I doubt anyone was flying a drone during a lightning and thundering storm...and through the woods? Not above the woods...THROUGH the woods. At 3 o'clock in the morning! Weird. Thoughts? Have you ever seen anything like this?
