A form of rapid transit that travels through underground tunnels, the subway may symbolize exploring the underworld and moving through psychological milestones to your destination of wholeness.
A subway may also indicate a preoccupation with getting to work and may reflect concerns in making a deadline.
Figurative of the wrong way; regressing
Dreams about traveling on the subway are highly symbolic.
If you have this dream, you may reach a goal in real life by using the spiritual or instinctive part of your nature.
Dreams of a subway represents your ability to move in and out of your own underworld, your ability to connect with your shadow, your depths and reemerge into light. See Goddess Persephone and Integration Dreams.
Interpretation of subways is based on your experience with this mode of transportation.
If you regularly use the subway, you may need to look at the other parts of the dream more carefully.
If the subway is not a regular part of your daily routine but is the primary dream image then you can consider it to be symbolic of the way that you navigate through your own emotions and hidden parts of self.
The subway is under the ground and represents the unconscious parts of self. All of us interact on conscious and unconscious levels. We have intuitive feelings and unspoken understanding that direct our lives as much as the obvious and fully conscious things. Consider the subway ride in your dream and try to understand what it is conveying to you about your more subtle navigation through ongoing life experiences. See also: Train
