Laughter in a dream can be interpreted as menstruation and I have certainly found this happening, especially when I think that I am not menstruating, but the dream appears as a vision to warn me that I am--laughter can thus be interpreted as menstruation because Lot's wife laughed because had suddenly begun menstruating, after menopause. This is one of the possible interpretations!!
That is possible. However, in the field of Quranic exegesis interpretations have to rely on either on textual evidence (verses of the Quran, hadith and athar) or on scientific evidence. Dream interpretation can only be admitted if there are Quranic verses or hadith narrations mentioning that seeing such a thing in a dream has such a meaning. If we ourselves relate menstruation and laughter through personal experience but this is not mentioned in Quranic verses or narrations, then it cannot be used to interpret the verse. If someone does a large-scale scientific study of women’s dreams and discovers a strong correlation between laughter in dreams and menstruation in the real world, then this too can be admitted as evidence to interpret the verse.
Also, note that the story related to Abraham’s wife not Lot’s wife.
