It can be anything really.
As an example;
Mine was being on a mountain high above the timber line big horn sheep hunting. We had to camp the night. And as evening came there was a lighting storm a few thousands feet below us and the Milky Way galaxy above us. The stars seemed so close and vivid, the clouds below lit up by the lighting flashes and we watched the sun set hundreds of miles away past numerous purple/red mountain ranges.
What did you experience that dazzled you?
Thanks for the great answers.
