This is almost exactly like my experience this morning. I made a post about it.
Can you try and explain what you were seeing with a little more detail? Was it an object/s, or more of a texture? Did it appear to be organic, or conscious? What kinds of colors were there? What was the "lighting" like?
Dark? Light? Bright? I'm really curious. Check out my [only] post, and see if you can draw any comparisons.
One big factor that made this more profound than all my other flights was that I had an omnidirectional perspective. Normally I only see things "in front" of me.
Why are you looking hard with a hood on and timberland boots, staring at me for one hour, when you could walk up and shake my hand?
Why are you making those mean faces in your videos with the fish lens effects?
Why do you walk in the clubs with 30 people around you and stand in the corner, with big bodyguards for no reason?
Why do you pull up, in valet parking, with your benz, that is rented? Fronting on a cellular phone that doesn't work.
Why are you smirking up your face, making obnoxious facial scenes like I supposed to be scared?
