Your mother's words gave you a hint. It makes you disgusted with the morality of society and makes you afraid of life. This influence has little effect on your thoughts, but it has a strong effect on hints. When your thoughts appear in your dreams.
Your father represents safety, you represent disgust, and girls represent fear. These three are displayed in your mind in the form of dreams. There is nothing to predict, just thinking during the day and dreaming at night.
