Dreaming of arriving at a house where your person is living with others can symbolize various aspects of your relationship and personal journey. The long hike you mentioned may represent a journey or struggle you have been going through, indicating that you have been working hard to reach a place of connection or understanding.

The house itself often symbolizes safety, comfort, and the foundation of relationships. Since your person is living with others, this could suggest feelings of insecurity or concerns about your place in their life. It may also reflect your awareness of their social environment and how it impacts your relationship.

Consider how you felt during this dream. Were you welcomed, or did you feel out of place? Your emotions can provide further insight into your current feelings about the relationship. If you felt positive, it could signify hope for integration into their life. If negative, it may indicate feelings of jealousy or concern about competition.

Overall, this dream might encourage you to reflect on your relationship dynamics and how you navigate your feelings about being with your person alongside others. It may be a call to communicate openly about your thoughts and feelings.
