I totally believe in signs and spent considerable time and effort learning a technique called "Sacred Signs" pioneered by Dr. Adrian Calabrese. Essentially, if you have a choice to make, she suggests that we can ask for a specific sign from the Universe, to indicate a course of action.
I had just become deeply interested in mediumship, several years ago, among many other interests, and wanted to ensure that this interest was beneficial in my purpose and role. I asked to be shown a caduceus, within 6 hours, to indicate I should continue the direction of my studies. A week before this a new tenant named Chris had put in a complaint about me. This is significant.
Just prior to the deadline, about 15 minutes, I heard a fire engine on the road outside and went to look. I was greeted to the sight of an ambulance instead with an enormous Caduceus on the side. Here's where it gets really weird. The ambulance had arrived because a tenant had died in the next building... and it had been the one who had put in a complaint about me a week before. I would not have paid much attention but it was so odd, that she would play such a huge role in my future studies.
