To see or play with a dollhouse in your dream suggests that you are idealizing a situation in your life. An area of your life where you believe that everything needs to be perfect or problem-free. A perfect and idealized view of home life or idealized view of your own personality. Negatively, you may be in denial about your problems or have problems asserting control.
Alternatively, a dollhouse in a dream may reflect a way to solve and work out waking problems that you want to see perfect. Relationship or social practice.
