Dear Elena,
I love all of your stories! I have heard of people having the birthing experience you described. It meant different things to different people. You said it might sound cliche to leave it up to God, but sometimes the only option we have is to leave it to God. Don't ever be afraid to say something because it might sound like a cliche. You are a very special person and what you say is important and has meaning to others, so cliche or not, say what you feel and be proud of it.
On the subject of seeing our past lives, One day when I was about 17 years old, I was listening to a Kurt Bestor tape (he has beautiful music) and this vision of a little blond girl running through wildflowers came to me. I could vividly see and feel everything around her and I felt so peaceful. At first I thought I was dreaming of heaven and that what heaven was going to look like for me, but the more I had the feelings I knew it was me and it was something that happened already in another life. I love to close my eyes and see me running through the flowers on a beautiful mountain top next to a cabin. Everything feels okay and peaceful when I remember this. I am lucky that I have a positive experience with seeing my past.
