Dreams involving animals, especially powerful ones like tigers, often symbolize aspects of our own feelings or experiences. In your dream, the tiger could represent a situation or emotion that feels threatening or out of control in your waking life. The man trying to put the tiger in a car might represent an attempt to contain or control something that feels wild or unpredictable.
Your reaction of running away and trying to close the gate suggests a desire to protect yourself from this threat. The gate symbolizes a barrier you are trying to establish to keep danger at bay. However, the fact that the tiger climbs the gate indicates that this issue may be persistent and hard to escape from, highlighting feelings of vulnerability.
Waking up just before the tiger pounces could indicate that you are facing a situation where you feel overwhelmed or that you are on the brink of confronting something fearsome. It might be beneficial to reflect on what in your life feels like it is out of control or what you are trying to manage. Consider ways to address those feelings or situations head-on rather than avoiding them, as confronting your fears may provide you with the resolution you need.
Overall, this dream suggests a need to evaluate the sources of your anxiety and consider strategies for dealing with them.
