Can the dreams of a menstruating woman, which she sees while sleeping in a state of ritual impurity, come true, or do they only come true if she is in a state of ritual purity?

Purity, or a woman's ritual purity from menstruation, is not a prerequisite for the truthfulness of a dream, although sleeping in a state of purity is more conducive to its truthfulness. It is recommended not to mention any disliked aspects of a dream to anyone, and to seek refuge in Allah from its evil and from Satan.
