Yes I have, and although I am not overly religious I do believe we have a guardian angel. I know I do.
I have told this story before on here, so apologies if you are re-reading it.
When I was late into my teenager years, I lived in a smallish city and if we were going out in the evening we wouldn't just stay at one place, but move from pub to pub. Sometimes we would get a lift with a crowd that had a car who were doing the same, but other times we would just hitchhike. This one night we were three girls and were sticking out our thumb for a lift, whilst walking close to the beachfront, but in a fairly secluded part where there was an open grassy area where we were walking. We were walking, talking, laughing and the next minute I feel a tap on my shoulder and I turn around and an elderly lady was behind me, and said to me, 'you shouldn't hitchhike', I turned back and around again to her and again she said 'please do not hitchhike'... I looked towards my friends, and then turned back to her, and there was no one there. Now where we were walking was a big open grassy area, but there was no one walking away from us. I was quite shocked and said to my friends, did you see the lady and they honestly to this day think that I made it up.
BUT, a few weeks later there was a terrible incident where a young woman was abducted from outside her flat, she was taken to an area not far from where I saw the lady, and the two guys slit her throat and left for her dead in the bushes next to the road. It was part of a satanic ritual apparently. She miraculously survived and crawled into the road, where a university student passed by and found her. I am not in the UK, but it is quite well known here, for this lady survived the incident, wrote a book about her experience and is now a motivational speaker.
But, I know deep inside that that could have been me. I think about it often. I do go through phases of guilt that it happened to her, other times relief that I have somebody watching me keeping me safe.
When dd was born, she was very ill. She contracted group b strep at birth which resulted in meningitis at 6 weeks. We were told at the hospital (this is another long story) that she had only hours to live. She was in hospital for quite some time and I stayed there with her, and I saw an old lady walk past her private ward a few times in the night. Nobody can just walk in and out of the paediatric ward at night as the doors are locked and coded. When she was a little older dd was sitting on her bed and chatting away. I went into the room to ask her who she was chatting to. She said to me ' to the lady there sitting on my bed'. She was even able to describe the lady, and as soon as she said, she has very thin lips.... I just knew.
I also see repeating numbers, in fact quite a lot lately... in the past year or so... and just so many co-incidences have occurred that really got me a little freaked out a few times.
