Dreams about being at a distance from a gathering or event, particularly a festive one like a Christmas party, can symbolize feelings of isolation or being left out. The setting of a beach might represent a place of relaxation and fun, contrasting with your feelings of anxiety and fear.

The phone call in your dream suggests a desire to connect or communicate with your employees, but being at home while they are celebrating could indicate a sense of responsibility or obligation that keeps you from fully engaging in social situations. The commotion and the idea of someone drowning may reflect your subconscious worries—perhaps about your ability to manage responsibilities, fears of losing control, or concerns about those around you.

Your inability to swim in real life could amplify these feelings of vulnerability and fear in the dream, especially with the drowning motif. It may highlight feelings of being overwhelmed or out of your depth in certain situations, both personally and professionally.

To address this anxiety, consider reflecting on your current relationships with your colleagues and any feelings of exclusion or worry you may have. It might be beneficial to find ways to connect more with them, even if it's outside of formal settings. Also, exploring ways to build confidence in areas where you feel vulnerable can be a positive step forward.
