To dream that the gate is closed parallels the notion that you are stuck in the current stage or phase of your life where you are unable to make progress. There may be some difficulties at hand which you lack the power and ability to resolve. Thus, these hindrances are keeping potential for better opportunities away.
At this point, you feel very frustrated and confused about where to go. Relax and try to resolve one issue at a time without losing focus.
Seeing the gate closed in your dream is indicative of your fear of letting others into your life. You fear that they will cross the boundaries you build and take advantage of your vulnerability.
