I don't know how to say, for example when you're talking and all over sudden become aware that you were wrong, I want to say "I had a moment of and I can't find the right word in dictionary. Because a lot of words in English language have Christian connotations, words the meaning of which includes Christian God, like "providence" "epiphany" etc. etc. etc.


all over sudden The expression is all of a sudden.

eg I had a moment of insight

eg I had an eye-opener

egI had a sudden realization

eg It suddenly dawned on me


If you're speaking casually, you can say,

"The/A light bulb went off (in my head)".

It means you suddenly understand something.
