Field trips are not only for school children. They can also be a part of your personal or spiritual journey. Spiritually speaking, you may have found faith in something you once did not believe in before.
Field trips can reveal new things about yourself that might change your perspective on life. This can lead to personal growth or transformation.
They represent a time when you have the chance to explore and learn about something new in the world outside of what you are used to. A field trip in a dream may signify the exploration of your own self-discovery and self-awareness, with new discoveries that await you in the future.
