Dreams about waking up in a strange place can often represent feelings of being out of your comfort zone or facing the unknown in your waking life. The rustic small town setting might symbolize a desire to return to simpler times or a need for grounding amidst chaos.

The large man you saw could represent a significant presence or influence in your life. His normal clothing suggests that this influence might not be as obvious or intimidating as it seems, but rather something that blends into everyday life. Not being able to see his face could indicate a lack of clarity about who or what this influence is.

Your brother's calm demeanor and childlike quality may symbolize a sense of innocence or purity in how you perceive this situation. His statement, "he's here," could suggest that you are becoming aware of a powerful force or change approaching in your life, which may be both daunting and significant.

Overall, this dream might be urging you to reflect on how you handle unexpected changes or influences and to tap into the calmness and support that close relationships, like that with your brother, can provide during uncertain times. Consider what new opportunities or challenges might be "arriving" in your life and how you can approach them with a sense of calm and awareness.
