Ooh - that makes sense. My shaman, when she looks in each of the directions for me, two times now has seen a rainbow bridge in one of the directions!
Also, there has been present - I can't remember her name but one of the goddessed of compassion who's symbol is the peacock feather with the rainbow colors.
I am seeing her again on November 8 of all days at 1:30 PM and we are journeying so I will be astrally travelling that day - should be veeeeeery interesting!
