Seeing “red mushrooms”
in your dream

Eating mushrooms in a dream means longevity, recovering of a sick person from his illness, marriage of an unwed person, acquiring knowledge, guidance, money or a job. (Also see Food)

See Truffle, as the same interpretation applies.

Up to three truffles symbolizes mean and useless or thankless individuals of either sex.
Truffles, like mushrooms, fungi, and plants that have no roots, symbolize foundlings, natural children produced by adultery, persons of unknown origin, and those who cannot stand on their feet, or money that comes spontaneously and without effort, like a gift, a donation, a grant, or any sudden and unexpected source of gratification. This belief is reinforced by the fact that the Muslims  Holy Prophet is reported to have said that truffles were a kind of manna, which, according to the Webster dictionary, is food miraculously supplied to the Israelites in their journey through the wilderness.
