Anyone else seen this before?

So years ago I was having a rough patch in my previous marriage and I couldn’t sleep. Being a smoker at the time I went out to have a cig at like 2am-ish I don’t recall the exact time but anyway suddenly I hear this odd tone that felt like it changed all other ambient sounds and by ambient sounds I mean I could hear frogs, crickets, birds, even an occasional coyote pack… This odd tone was damn near subsonic if not completely. Then suddenly a very bright craft wayyyyyy up like satellite altitude shows up, and it was huge.. just one light and so high that all I could see was the light, no body shape or craft that I could make out but again the altitude was the reason. This object was moving roughly 10X faster than anything else up there and it just crossed the horizon and disappeared BUT the really freaky part was that it changed the tone of the sky behind it as it passed.. the light behind it was brighter and the sky in front of it was dark and normal like before the sound or craft showed up. It looked like this thing pulled back an invisible curtain that was holding back light. Once it was completely gone the sky stayed brighter (the tone it became as this craft went by)

Fast forward a month.. I had the same sighting again similar time of night. I felt and or heard that odd subsonic sound, the craft came into view and had brighter light behind it than it did in front of it and once it left the whole sky was stuck in that more lit up state.

Background on me:

I’m not crazy I swear haha 🤣 for real though I worked for a govt contractor repairing f22 turbines and various other military tech. Not only do I understand military tech but I’ve seen it and have been trusted with it..
