I am new to this site but have read a story that is so similar to mine about the spirit that I felt that I should share my experience and would live feedback about this or if you have see it please email me at clayweir2[at]yahoo[dot]com.
This happened when I was 13 years old in Huntsville, Alabama. My friends and I were out free running and that entire day I had a headache that was worse than anything I had ever experienced.
So at this time we were around the Huntsville Hospital and my friends were around the entrance so I went inside to get a drink out of the vending machine when this lady in a Red Cross uniform approached me out of nowhere. At first I thought I was in trouble for jumping around the hospital, and especially when she said to call my mom to come up here. But when I asked if I was in trouble she simply replied no but you're going to be soon if you don't come with me.
She led me to a desk and told me to say I was suffering from a brain aneurysm. (Of course being 13 I had no idea what that was). So then I was rushed into surgery and woke up 2 days later. I saw that nurse only once more as I was leaving, she was standing in the ambulance dock and waving happily. I later asked about her but the hospital had "no record of anyone like that working there".
I would like some feedback about this any if anyone has experienced this as well. If you would like to contact me my email is above and I would love to hear from you. This spirit saved me and I would love to know more about her.
