I had a boyfriend and he was a sea person and we were together and happy, but then he left because he didn’t want my parents to split us apart
In dreams, water is often symbolic of emotions and feelings. Your dream is reflecting your desire for a happy and fulfilling relationship with someone special, who cares about you and makes you feel comfortable.
The presence of your boyfriend being a sea person refers to his depth, and how deeply he connects with you emotionally. However, the departure may indicate your fear of losing him or some apprehension that your relationship might be affected by external factors.
The fact that he is leaving because he doesn't want your parents to split you apart may signify your anxiety over parental interference in your love life. This dream may suggest that you feel restricted in your romantic pursuits because of your family's expectation and may fear that your relationship may not be able to withstand outside pressures.
Overall, this dream highlights concern and uncertainty on your part that you might not be able to maintain a relationship on your terms. It might be a good idea to assess whether your fear of parental influence is impacting your relationships.
