Snow in a dream is sustenance, healing, and spoils if it is in its season and causes no harm. Out of its season, it indicates illnesses, worries, and strife. Walking on snow indicates striving for a matter involving danger and delusion.

Snow indicates wealth and fertility. If the snow is little, it is good. If it is a lot, it is torment. Eating snow in summer indicates the removal of worry, and in winter, it indicates illness.

Snow is interpreted as torment and soldiers. Its fall in its season indicates low prices and the removal of worries. Out of its season, it indicates the injustice of the ruler.
