To see a gate in your dream indicates that your life is changing for the better. You can see it as new opportunities coming your way, especially if the gate is open or swinging. If the gate is closed, it suggests that you are having trouble facing your current difficulties. If you fail to open the closed gate, it means you are underprepared or not ready to go to the next step.
If you see yourself climbing up a gate, it means you are trying to see what lies beyond that gate. You want to be sure before committing. But if you climb over it, it indicates that you are impatient and want a cheat code to life.
