Dreams about zoos often symbolize a place of confinement or control over wild aspects of the self or others. In your dream, the zoo closing forever may represent a significant change or transition in your life, perhaps indicating the end of a particular chapter or the need to confront emotions or situations you've been managing.

Being alone with your dogs suggests a connection to loyalty and companionship, highlighting the importance of relationships in your life. The lions escaping could symbolize fears or challenges that feel overwhelming, yet their friendly behavior indicates that what you fear might not be as dangerous as it seems.

Your climbing the fence to escape signifies a desire to protect yourself and those you care about from potential threats or chaos. The act of calling for help shows your instinct to seek support during times of fear or uncertainty.

The presence of someone you know who ultimately lets the lions out might symbolize a part of yourself or someone in your life who helps you navigate through fears, ultimately leading to a resolution.

Overall, this dream could be encouraging you to face your fears, recognize the support you have, and understand that sometimes what seems threatening may not be as harmful as it appears. It might be beneficial to reflect on areas in your life where you feel confined or challenged and consider what changes are necessary for your growth.
