Probably a ufo that realized you were staring right at its camera...so it went incognito mode for a bit.

I have no idea. We're due for some cataclysm though.

I, for one, believe you. I have no theory or explanation, but 4 times in my life I wanted outlandish, impossible things, to happen, and they happened to my startled and shocked horror. It was NOT deja vu (reverse thought confusion) it was actual sequential WISH-followed by - EFFECT. Each time the thing I wanted was subtle and took little energy to cause, but all involved potential energy waiting for small nudge... to make the dramatic effect occur. I have not done it in decades. Now that I think hard, I can list 6 such events and 2 more bizarre impossible coincidences. All done in my early 20s, and I was hyper agitated at each time. https://en.wikipedia.org/wiki/The_Secret_(book) https://www.thesecret.tv/ https://www.thesecret.tv/product-category/books/ https://www.imdb.com/title/tt0846789/ https://slate.com/human-interest/2007/05/what-happened-when-i-followed-the-secrets-advice-for-two-months.html Scientific explanation for your observation : many so-called stars are just mid altitude satellites that shine either bright or go full dark, depending on angle of reflected sunlight on a facet of the satellite. Time lapse photography can show these events every night. https://en.wikipedia.org/wiki/Satellite_flare video gif of what you saw : https://en.wikipedia.org/wiki/Satellite_flare#/media/File:Iridium_animation.gif

That star could have dies millions of years ago and it took that long for the light to stop reaching earth
