What happens to the human soul during sleep, and how does it leave the body and go to the world of Barzakh, and how are dreams formed, knowing that a righteous vision is from God and a dream is from Satan, and is there a scientific aspect that does not contradict the religious position on this?

Thank you for contacting us. We inform you that explaining the subject of the soul from a scientific perspective is not within our purview; you may consult specialists in this field. Many matters concerning the soul are hidden from humans, as Allah Almighty said: "And they ask you, [O Muhammad], about the soul. Say, 'The soul is of the affair of my Lord. And you have not been given of knowledge except a little.'" For more information, please refer to Fatwas no. 36702 and 38180.
