If you were dreaming of a doll, it could be because of your nostalgia for your childhood and your toys.
There is a possibility that if you had spent time with a doll during your day, it might trigger a dream about a doll.
To dream of a doll can mean the dreamer feels disorientated or unhappy in her identity. A doll is artificially made up to look pretty. The dream symbol represents what the dreamer thinks they are, during the day.
