What does a Gate in a dream mean?

A Gate in a dream can represent:
Barrier
Entryway
What is open/closed
Passageway to somewhere new - are you entering into a new era in your life?
A closed gate or one that is locked to you may represent your fears of the unknown, or perhaps you feel that you aren't ready for what lies on the other side.
Opening a gate into someone's house can be a pleasant and welcoming symbol.
