Understanding sexual dreams can help the dreamer overcome guilt and shame
Erotic dreams might be a means to compensate for the absence of sex in one’s life. Suppression of sex, even its discussion being taboo, makes it a potent force in the subconscious mind.
Sexual dreams can as well be a metaphor for an unresolved situation in your life. So a proper understanding can lead to personal growth.
Dreams also provide people with a neutral space where they can go beyond their inhibitions and overcome their fears regarding sex or certain behaviour.
A dream featuring you and someone you share a platonic relationship with might hint at further cementing of the close relationship with that person.
If a boy under parental pressure to study all the time has sex in a dream, it could just mean that he needs to take a break from his studies.
If a person dreams of having sex in a car, it might imply that he wants to own the car—sex becomes a symbol for ownership.
