I have not read about too many other's NDE's but I can tell you from what I went through, I think you must have had a NDE or a trama related Out of Body Experience... How exciting! I love the part about your baby and about your Grand ma saying it isn't time yet... I love the whole thing... Your experience makes me remember my NDE so well. When you came back, did you have a different outlook on love and the world etc... Please tell us more... Gosh...I just love it!
Lately, I have been remembering God... God knowing me before I was born. I think time is just an illusion and the pre-baby baby in your experience re-affirms this odd sort of knowing about being a spiritual being before we are born. How old is your baby now?
