Nikki,
Your dream suggests that you may be feeling some discomfort or unease within yourself. The stomach is often associated with our emotions and instincts, and when we feel something in our stomach, it can be a sign that we are processing something emotionally. In your case, the fact that you are feeling something inside your stomach may indicate that there is something that you are not fully acknowledging or expressing. It's important to try to identify what these emotions are and allow yourself to feel them, as suppressing them can lead to further discomfort and tension.
This dream interpretation is based on the information you have provided about your age and relationship status. As a young woman, you may be experiencing a range of emotions as you navigate new experiences and challenges. It's important to remember that it's okay to feel a variety of emotions, and that it's important to allow yourself to experience them fully. Suppressing or ignoring your emotions can lead to problems down the road. If you're feeling overwhelmed by your emotions, it may be helpful to talk to a friend, family member, or therapist. They can provide support and guidance as you work through your emotions and develop coping mechanisms.
