Is a dream vision after the Istikhara prayer considered an indication that the matter for which Istikhara was sought is impermissible, and must one act upon it in the decision to travel after seeing deceased people in the dream?

Visions and dreams do not form a fundamental basis for matters of religion or worldly affairs. The questioner must obey her husband by traveling to him and not paying attention to dreams, especially if they are from Satan, as confirmed by the Prophet, peace and blessings be upon him: "A good vision is from Allah, and a bad vision is from Satan." She must rely on Allah and obey her husband. The Prophet, peace and blessings be upon him, guided to the remedy for a bad dream by spitting to the left and seeking refuge with Allah from the accursed Satan.
