If you dream of turning in your sleep, it may indicate significant changes in your life. This dream suggests that you might be drifting away from your beliefs or values, which could negatively impact your life. You may face financial loss or deterioration in relationships. Therefore, this dream serves as a warning for you to reconsider your decisions and focus on your core intentions.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Turning in one's sleep" (page 451).
If one sees himself turning in his sleep and putting his face down, or resting on his stomach in a dream, it means that he will turn away from his faith and lose both his earnings in this world and in the hereafter. If one sees the reverse, which is turning from resting on one's stomach to lying on his back in a dream, it means that he will repent for his sins. It also represents his willingness to face the people and to correct his wrongdoing. If the subject is a woman, then sleeping on her stomach in a dream means that she is refusing to sleep with her husband. (Also see Running away; Take a flight; Sleep)
