In my wet dreams I see ghair mahram females some of whom I know, and some I don't know.

Answer

Generally, one is not liable for the evil one sees oneself committing in dreams. However, sometimes there is a relationship between the two states – what one does when awake and what one dreams. If during your wakeful hours you fantasize about ghair mahram females, then such fantasizing is recorded as zina. In terms of the Aakhirah, you will then be apprehended for zina. If you are indulging in such haraam fantasizing, then it will influence your dreams. Since the haraam fantasizing during wakeful hours, and staring at females lustfully result in seeing the ghair mahram females in the wet dreams, the sin is simply confirmed by the dream. The 'zina' in the dream is the effect of the zina of the mind and eyes committed while awake.

If the appearance of women in wet dreams is not the effect of haraam fantasizing, it is not sinful.
