Have you ever had a religious experience?

I was put under ether for surgery when I was young, decades ago. Suddenly it seemed I was sitting on the fence in the of the house I lived in. The fence happend to be at the crest of a hill and the land sloped away slightly on both sides. Then suddenly there was some kind of a flat surface in the vertical plane of the fence. Then I was IN this plane as a 2-dimensional being, something like the bad guys in the Superman II movie.
Then I had a pfeeling I could fall either forwards or backwards out of the vertical plane surface. I fell back and into a multi-dimensional place that was full of a golden light and a warm fuzzy feeling of total knowlege (which I could not keep). I felt I had been here before.
Then suddenly I was a little black ball that was contracting exponentially ever faster as it was vibrating in exponentially ever faster in oscilations of exponentially ever greater amplitude. I also felt I had been here before too. Then the thought hit me that there was no limit to how bad this could get, and I abandoned hope.
Then I woke up in the hospital ward and literally wept with relief.
Then I reached out and took the daily newspaper from the bedside table and read an interview with Aldous Huxley (who was still living at the time). He was an early researcher and author on halucinogenic drugs. He said in the interview "we may be too deeply steeped in the situation into which somehow or other we seem to have stumbled, and out of which the question arises, to ever find an answer to it". And I never forgot that quote. Although I have never been able to find it again in later days by Google searches. I was impressed he could see reality in that perspective, but I felt his speculation was wrong because I believed I had just transcended the situation.
I was sure in my own mind I had just seen heaven and hell, and the rest of my life would be an epilog. Yes it was a drug-induced experience. Ether. But that doesn't mitigate the subjective experience.
