Hello! Nice post. But...it is individual first and then perhaps collective. How do I know that?
Because your first lines about eyes and ears has happened in me and other individuals; but, not everyone. The bit with eyes is a variation of Rev 1:7. “Behold He cometh with clouds and every eye shall see Him.” For me, my outer vision went white, with slight alterations so that it was similar to a completely overcast sky filled with white clouds, which in hindsight I saw with my inner eye. I was temporarily blinded.
And the ear bit in your post will begin like tinnitus. Many, many spiritual folk have acquired a tinnitus-like sound in their hearing recently, including myself. “The Spirit blows where it intends and you hear the sound thereof...the same is true of everyone who is born of the Spirit” John 3:8.
