can symbolize ignorance, especially if it conceals everything, but its shape usually tells the dreamer the essence of his mental problem or block.
can sometimes be considered a mediator between the spiritual (above) and the instinctual (below), then it can help the instinctual content in emotional development (with rain) or even in spiritual development (with snow or lightning).
everything in the sky covered by clouds: symbolizes ideas or spiritual symbols that the dreamer is still unable to realize and understand.
buildings or other human works reaching up to the clouds: the notion of a center of being (see Treasure archetype).
a cosmic cloud of planetary dimensions: a frequent vision accompanying a person's spiritual development and is often complemented by an apocalyptic catastrophe with a devastating impact on all earthly life (for more on the three-day eclipse and the possibility of seeing into the future see the Past and Future Visions archetype).
clouds and wind: the spiritual essence of wind is able in one strong gust to remove clouds (ignorance) and to clean the consciousness of unnecessary ballast.
rapidly moving clouds that disappear: foretell serious events affecting all of society.
