Example: Having been enjoying ourselves with some work mates at a social club, my husband and I are travelling down a country lane in an open horsedrawn carriage. It is dark. We come to a humpbacked bridge. As we arrive at the brow of the bridge a voice says, “Fair lady come to me”. I float and everything is black and peaceful. Then great fear overcomes me. I wake with terror and feelings of horror* (Evelyn K). Evelyn’s dream paints a vivid picture of her journey through life, drawn by the natural forces within her, shown as a horse. She has enjoyed life, but comes to the brow of her life, her 40th year, and feels it is all downhill now into old age, which horrifies her.
The bridge generally has this significance of crossing from one phase of life, activity or emphasis, to another. It depicts connection between yourself and a relationship; self and opportunity; self and change in life. Fallen bridge: lost opportunity, broken bonds and connections. Idioms, burn one’s bridges; cross that bridge when I come to it; water under the bridge. ... A Guide to Dreams and Sleep Experiences
