What does it mean when you dream of a rainbow bridge? This probably means a rainbow in the sky which looks like a bridge. Humans can’t walk on this bridge because they have weight and the rainbow is not a physical construction that can take the weight.
Maybe the only way a human image can walk on a rainbow bridge, is when the image is not of solid mortal being, but a spirit/ soul/apparition. It means the human is dead. Jung, in his writings, said only “gods” can walk along rainbow bridges.
