i walked out on my deck to watch the skies like i do every night that time and I immediately noticed 3 very bright lights in a line

i have a video of the incident. there were 3 very bright lights in the night sky, way brighter than the stars, and they were lined up in a perfectly straight line.
they looked as if they were blinking or the lights were going in and out of view, not in harmony. they sat there until i went inside and it freaked me out for days now. I routinely go outside on my back deck and watch the skies at night waiting for sightings and this was outside above my house. i have it on video. i know my view of the sky very well and this was never there before which prompted me to start recording. to reassure myself that it was one giant craft or three individual craft, and not orions belt, I have been monitoring the exact position of the sighting every night at the same time and what i saw has not returned and cannot be found in my sky anywhere since the sighting. very strange. while looking in its direction my vision felt distorted like the image was wavy as well. blew my mind. my dog began acting very strange and barking and hiding under the deck table as well. hes a huge dog too. he was freightened.
