At a crossroads
Do you feel like you've lost your focus? That's what the lost schedule brings to mind. You indicated that you're in your late 20s, a time when we often feel pressured to start making our mark on the world. As such, the dreams may be a wake-up call to set some stronger goals, or perhaps to rethink the goals you already have, so they align with your life's purpose. Is your work challenging and fulfilling? Are you growing professionally, or are you stagnating at a job that's too comfortable? Or perhaps you need a complete change of direction?
Going back to high school and trying to find your class may indicate you feel unprepared for the next step in your life. Whether it's your career, love life, or something else, you may be stuck in the past and need to move forward in certain areas of your life. Do some soul-searching to see where you need to grow, both personally and professionally.
