You've, no doubt, read about the Transfiguration, including all the details about those present falling asleep and what they witnessed when they were roused back to consciousness.
There had to be at least the briefest of moments, among any one of those present, that separated being asleep and being awake again, witnessing something quite extraordinary.
Or perhaps it's like that momentary "lag" before they were even able to be stunned, before they could react in any fashion whatsoever, like when lightning strikes very close by and that instant before most folks tend to jerk, before thunder envelopes them.
Without going burdening anyone with a windy commentary on the whole phenomena, let's just say I sometimes feel like my "response" must be similar.
Many things, of course, happen too fast for our minds to fathom, and we just don't have time even to formulate a reaction of any kind, except the feeling, so to speak (because it's really not a 'feeling,' as such - more of a "pre-feeling"), in what I'm laboring too hard to describe just goes on and on.
That is to say, I am Peter, perpetually in the interstitial place between his becoming fully awake to his transfigured Lord nearby and when he started babbling, trying to justify his being present, praising Jesus decision to invite them up the mountain to see this astounding scene and organizing a building committee.
You'll recall, of course, that a cloud descended on the scene and a voice from the cloud may have set things right about a proper, better response.
"This is my Beloved Son, with whom I am well pleased," this voice is reliably reported to have said. "Listen to Him!"
The only response I’ve ever been able to muster is “Thank You,”
As for what you described, I am not even going to try.
