THE RAINBOW BRIDGE
In Norse Mythology the Rainbow Bridge was a walkway that stretched between Midgard (the world) and Asgard, (the realm of the gods.) Those who crossed it did so into the divine world and from the divine world into this one.
The famous Poem "Rainbow Bridge", describes a bridge where dogs cross into the afterlife. Overtoun Bridge is the only real life Rainbow Bridge in the world. It has been dubbed "a thin place" where heaven and earth have overlapped, and where supersensitive dogs are sensing a portal into another world.
