Dreaming of returning to your childhood farm can symbolize a longing for your roots or a desire to reconnect with your past. The rundown and overgrown state of the farm might represent feelings of neglect or unresolved issues from your upbringing. The presence of strangers suggests that you may be facing unfamiliar challenges or changes in your life that are causing you to feel overwhelmed.

Crying in the dream indicates a release of pent-up emotions, possibly related to nostalgia, loss, or unresolved feelings about your past. The fact that your brother was with you and waited while you wept could signify support and comfort from family, suggesting that you don't have to face your feelings alone.

Overall, this dream may be an invitation to reflect on your past, process any emotions tied to it, and consider how they may be influencing your present life. Allow yourself to embrace these feelings and seek support from loved ones if needed.
