First, your dream is awesome, from now I'll start a meditation as you do. My humble advice: try to find out keys in your dream, because in those things that go unnoticed, you can find the real answers.
The number 3 is very important for many religions, is the number of the plurals and the birth. Why? 1 is the individual, 2 the couple and 3 the plural, the choosing, the way, the beginning. That which is born by the combination of the couples (1 and 2). Because of that, this number appear in the sacred composition of humans: father, son and holy ghost; Odin, Vilje and Ve, etc etc... In summary, body, soul and conscience.
I hope this can help you.
