Your right: At a certain point you don't need proof, you just have visitation.
Your reply just reminded me too.
Sometimes they do leave gifts.
A couple of months back I was teaching a couple of kids about certain things, it was raining and I was sharing the vids I Had for seeing two ufos over that pub early summer, and it was getting dark so very low visibility, no point in looking up to see my friends in the skies. So instead they sent us angel hair. Not sure if you know what that is or not, it's when 5d materials interact with 3d materials and a plasma discharge from the spare electrons transmutes nearby environmental chemicals within a certain radius. Because it's a by product of a higher density than ghosts it's like a thinner form of ektoplasam. Usually evaporates quickly...
So anyway, sitting talking, outside, sitting on benches, and this pile of the stuff comes floating through the air, would have been about the size of a plastic bag flying by, but it was more like cotton ball or bubble wrap, bubble wrap for its glimmer and reflections, cotton balls sort of exploded into a filament ball.
About ten maybe 12 other people saw it and were staring.
It landed in the space beside the pub on top of a fire escape. most lost interest there.
I was later walking them around to the local taxi rank and more of the stuff appeared in front of us, it was a smaller bundle of it this time, about a pillow size I guess.
Got two pics of it before it evaporated.
The guy I was with ate some, for what ever reason, it had no taste.
Felt strange to touch too.
By the look, you would almost think it would pop like bubbles would, but it just vanished bit by bit and you couldn't even feel the weight of it.
