Dreams about drowning or being submerged in water often symbolize feelings of being overwhelmed or out of control in your waking life. The boat could represent a sense of safety or companionship, but the act of your friend pushing you down might suggest feelings of betrayal or being held back by someone close to you.

The struggle to get back to the surface reflects a desire to regain control or escape a challenging situation. Feeling like you ran out of air and surrendered indicates a point of exhaustion or acceptance of certain circumstances that may be affecting you emotionally or mentally.

This dream could be urging you to assess your relationships and personal boundaries. Consider whether there are situations or individuals in your life that are causing you stress or making you feel powerless. It might be beneficial to communicate your feelings with those around you or seek ways to empower yourself in challenging situations.

Overall, this dream serves as a reminder to pay attention to your emotional health and to seek support if you feel overwhelmed.
