My experience was more of a feeling...
I didn't have one experience that made me believe I was more than my ego and body, I had this "feeling" that I knew there was more to me and life and I knew this feeling had to do with God.
For years, I just went off this "feeling." This "feeling" was my solace when I went through any struggles in life. I would go back to this "feeling," reaching it through meditation or prayer and I would feel comfort, happiness, and love.
As I got older and began to understand my psychic and intuitive experiences, then I began to have more "out of body" or spiritual experiences that would show me I was more than my ego and body.
