How to interpret a dream involving dolls 
Recognize the doll as a potential childhood symbol. 
Dolls are consciously associated often with childhood. It makes sense that this association would cross over into the subconscious realm.
If you're having any thoughts about your childhood during your waking life, you should become more mindful of what they are and how they might relate to the doll dreams you've been having. Look for recurring symbols in your dream and life.
