What is the legal interpretation and appropriate guidance for the case of a woman who has reached the age of forty, facing repeated setbacks and calamities befalling everyone who proposes to her after initial agreement, which leads her to withdraw out of fear for them, and what is the interpretation of her dream in which she saw a black insect (gecko) and birds, bearing in mind that she has diligently performed Istikhara prayer and recited the Quran?

What is happening to you is Allah's divine decree and destiny. You must submit to it and say: "Indeed we belong to Allah, and indeed to Him we will return," and "Allah has decreed, and what He willed He has done," and "O Allah, reward me in my calamity and replace it with something better." This should be done while avoiding pessimism. If it is highly probable that it is magic or envy (hasad (definition)), then seeking treatment for them is permissible, knowing that a dream after performing Istikhara is not a condition for its validity, nor does it lead to a practical ruling, because its interpretation is speculative.
