Personally I had a interesting experience with the Angel Raphael. This angel is associated a lot with travelers - my husband was driving and I was imagining angels on top of the roofs of other peoples vehicles and also on top of our own.
It was like my imagination took on a life of it's own (it was working without having to imagine anymore). The angel on top of my car turned to look at me and made a hilarious face at me, which made me chuckle - then this angel was using my car like a surf board weaving in and out of traffic. I would get little goose bumps throughout my body every time I acknowledged her.
I actually figured out later that it was Raphael by doing a little reading on one of the sites I told you about. The humor, and the fact that Raphael is known for travelers made sense to me that it was indeed Raphael.
