I had a similar answer to prayer, i.e. where words fail.
It was years ago and I had prayed asking God about the crucifixion. He gave me a mental image of a great Light coming from the Cross, extending over all of space and time - and innumerable tiny bubbles (us) rising up from the darkness and disappearing into the Light.
His answer wasn't in words and I could never paint it (wish I could) - but I am certain now that Christ's blood is timeless, it reaches to those in the past, present and future.
[ I so enjoy hearing your testimony about your vision, dear hosepipe! I had a similar answer to prayer, i.e. where words fail. ]
During my “vision” it was like being wide-awake in a dreamy state with images but no words spoken.. I could write on my word processing software.. which I did.. The images were poignant and obvious and ideas about them appeared in my “mind” (no words)... I knew those ideas were not “mine”... Not scary at all.. but ebullient..
This happened in the morning after my prayer time.. for about an hour maybe 30 minutes then it went away and I performed my daily functions as usual.. With many of the images to think about.. This happened for about 10 days in a row maybe 12... can’t remember.. hasn’t happened since..
Its taken me several to process this data somewhat... Two of the “ideas” being 1)designated and 2)UN-Designated energy/matter.. there were and are many more... I had and still have no idea what those two can be.. actually.. but they are interesting concepts.. The “merging of spirits” or “spirit creatures/beings/us/whatever” was displayed in images.. Of course; I cannot fully explain it/them/the experience.. a very personal “image” of it happening..
I wonder if your experience was in kind... It’s hard to explain in words things that there is/are no words(I know of) to explain it/them.. Just the concept of language becoming obsolete floored me, just blew me away.. What is to replace language is the stuff dreams are made of.. i.e. merging..
