Foam / Froth dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Klaus Vollmar
This image is connected to the Venus symbol, Water and Air fusing emotion and intellect and representing redemption.
The same symbol, however, might reveal a tendency toward unrealistic ideas and plans—”the hot air merchant”—indicating a tendency to blow things out of proportion, to exaggerate; or it may simply point to necessary cleansing.
