<The interesting thing about your dream is; what was/is the significance of this particular word ? (In the context of your life). >
Thats the weird part. There is no significance, because I've not heard of it. I've heard of vigilant, but not that word. The way I heard it in the dream was pronounced VI GAN TUH LISM.
I have dreams that have come true too. Some are very weird, because I have no connection to some of them at all. Once in my 20's or early 30's, I had a dream of a wooden door with a curved top, with the word "Druids" painted on it. I had not heard of the word until my sister in law told me what it was. Another time, I dreamt of an old church in Canterbury, and there were no Canterburys in my area (NJ).
