What does wonder wall mean to you?

https://youtu.be/6hzrDeceEKc?si=RpAH-ehzyyH5ic8M Wonderwall to me means it's the wall the person creates that seperates you from the darkness trying to get a hold of you. You listen to that person more than you do the darkness. Wonderwall is your protector that ultimately saves you from yourself. For me my gf is my Wonderwall.
