They absolutely are, even if we as believers are not aware of them.
In college, after years of indulging myself, I became increasingly convicted of my sin. This started, apparently, for no reason I could see -- nothing human had done it. I had had practically no religious upbringing or training and was at that time interfaced with no Christians whatsoever. No one had preached anything to me. In fact, when in junior college I recall laughing at two students dressed as clowns who were going around handing out Gospel tracts. "Hah! Clowns for Christ!" I laughed as they walked by. Indeed they were (1 Cor 4:10). That memory still shames me.
But some time later, after the conviction became unbearable and after much screaming resistance of the flesh, I finally heard and believed the saving Good News. The changes in me were not immediate but they did take place. I found this almost shocking because I was not told to expect much of anything (the people who led me to Christ were rather weak and doctrinally disordered themselves, but thank God the Gospel itself is His power unto salvation, not any preacher or preacher's delivery). So in due time, not only the obvious things I thought needed changing did change, but things I did NOT want to see changed, also changed.
Most telling for me, though, was when things I never even thought about as needing changing, also changed.
The point is, all of these - whether I wanted them changed, didn't want them changed or never thought of - were changes I could not have effected even if I'd wanted to. But God did them anyway because that's how our gradual growth into the image of Christ starts.
I don't understand why you think this experience should matter to anyone else. Or why you think the lessons you took away from it apply to everyone, and are the only possible lessons that could be taken from it.
When I was a small child, I had a direct personal experience of God. Not in church, not with anyone else, just me and God. And it was amazing in ways that I cannot possibly explain away. And it effected the way I relate to religion and religiosity for the rest of my life.
Yet I can't think of any reason why this event in my life should mean anything to anyone else. Nor why the lessons I drew from it should be the lessons anyone else should draw from my telling them about it. I'm not belittling your experience, nor my own, but they were OUR experiences. And the significance we give to them is a significance relative to ourselves, alone. There is no reason anyone else needs to feel that our experiences are applicable to them, or that the lessons we drew from them are lessons that others need to apply to themselves.
I was an active member of AA for many years, and have heard a lot of people tell their life stories. And I can tell you that there are a lot of folks out there with some truly amazing and inexplicable experiences in their lives. Things have happened to people that you would have great difficulty believing, and yet I believe the people telling these stories are telling the truth. Life is a lot more mysterious than we humans want to acknowledge, and we know far less about what's going on around us than we think we do.
Those of us who have experienced these kinds of amazing events have to just do the best we can in the wake of them. We take the lessons for whatever they're worth to us, and keep moving on. But we have to realize that we still don't really understand them, even though we may think we do. Just as we thought we understood things before these events happened and then changed our understanding.
"One revelation does not a sage, make." And revelations are personal. They don't apply to everyone; only to the one experiencing it.
Proselytizing is for cult members and con men. The real sage knows it's only advertising for the ignorant; and it's pointless.
But you do as you please.
