Dreams involving portals often symbolize transitions or significant changes in your life. In your dream, the digital world suggests a sense of comfort or a controlled environment, possibly reflecting feelings of safety within your family and loved ones. When the portal opens and begins taking people, it may represent unexpected changes or challenges that threaten your sense of security and connection.

The act of your boyfriend pushing you away before being taken could indicate feelings of abandonment or unresolved issues in your relationship. This aspect of the dream might be prompting you to reflect on your emotional ties and the dynamics of your relationships.

The scene with your mother pushing the car signifies a strong bond and willingness to sacrifice for family. Her decision to stay behind could represent feelings of guilt or the idea that sometimes, loved ones may make sacrifices for the sake of others' happiness or safety. This could also point to your fears of losing connections with those you care about.

Overall, this dream suggests a deep exploration of your relationships, your fears of loss, and your desire to remain connected with your loved ones. It might be beneficial to communicate with those close to you about any feelings of anxiety or disconnection you may be experiencing. Consider what changes are occurring in your life and how they impact your relationships.
