Is there another way to undo the magic, after the photographer refused my underwear and sensitive area, given that none of the signs of an enchanted person apply to me?

What your friend saw might be from Satan, and the interpretation of dreams mentioned by that woman might not be correct. She could be a sorceress, given her request to photograph intimate parts, and you did well in refusing to comply with her request. You should not pay attention to what your friend saw. And whoever sees something he dislikes in his dream should spit to his left three times, seek refuge in Allah from the evil of what he saw, and not tell anyone, and he should maintain the remembrance of Allah before sleep. Both of you should fortify yourselves by regularly reciting the prescribed dhikr, and there is no harm in using lawful ruqyah (definition). You can seek assistance from raqis (exorcists) who are known for their uprightness and avoidance of charlatanism.
