Hello Ja,
Thank you for sharing your dream. I confess it was a little bit difficult discerning what you are trying to say. Please take whatever I share to the Holy Spirit as He Alone gives the interpretation.
Are you a Christ-follower? It sounds like there is a conflict of some sort regarding careers. Are you currently teaching students? Are there obstacles for you trying to become a nurse? Is someone hindering you from becoming a nurse? (i.e., stop sign)
Just some questions to ponder from a literal perspective.
Alternatively perhaps there might be some people (perhaps young in faith) that you would rather nurture (i.e., “nurse”) than teach.
Shalom,
Cheryl
