Tianna, your dream is quite rich with symbolism and emotional undertones. Being with your ex-best friend, who has taken the form of a vampire, suggests that there are unresolved feelings or conflicts between you and this person. Vampires typically symbolize something or someone that drains your energy, which might indicate that this past relationship had a taxing or detrimental effect on you. The fact that this person is an ex-best friend can also point to feelings of betrayal, loss, or unresolved issues that linger in your subconscious.
The element of you having a baby and giving birth is equally significant. Birth in dreams often symbolizes new beginnings, personal growth, or the development of new ideas or aspects of yourself. Given your experiences and the challenges you've faced, this might suggest that you are in a phase of transformation, trying to bring forth a new version of yourself, perhaps one that has overcome past traumas and difficulties.
Combining these elements, it seems your dream is reflecting a struggle between the old and the new. The presence of the vampire could represent past influences or memories that still 'suck' the life out of you, while the act of giving birth indicates your potential and desire to move forward into a healthier, more fulfilling phase of life. It may also be highlighting the inner conflict between holding onto past grievances and the necessity to let them go in order to nurture new beginnings.
