What does it mean to dream about my baby daddy's girlfriend?

Dreams are about the dreamer: your feelings, your thoughts, your intuition. Dreams do not contain any reliable information about anyone else, so a dream is not evidence that the partner is cheating. However, dreams can point out subtle patterns of behavior that might be ignored by the waking mind. This dream could just as easily be about the dreamer's unfounded jealousy. Such dreams must be carefully considered and at best, they can lead to open, honest communication.

it means you guys dont have a good relationship meaning you dont bond well and asuming its all about work. it could also mean they are cheating or having an affair with another someone. you just have to work it out.
