Dreams about houses often symbolize the self or your personal life, and in your case, the house you shared with your in-laws might represent feelings about family dynamics and your current relationship with them. Being locked out suggests feelings of exclusion or a desire to regain control over your personal space and belongings. The act of seeing your possessions being taken can reflect anxieties about losing your identity or autonomy in a shared family environment.

The transition to a mom-and-pop shop could indicate a need for comfort or a desire to retreat to a simpler, more familiar place. It may also suggest a search for safety and security, especially in light of feeling threatened by family members you haven't spoken to in years. This can symbolize unresolved issues or conflicts within your family that you might be trying to navigate.

The presence of a love interest could signify a desire for emotional connection or support amidst these family tensions. It may represent a need to focus on your relationship with your fiancé and the desire to establish boundaries with family members.

Overall, these dreams may be encouraging you to address your feelings about family relationships, assert your independence, and seek clarity on your identity within your current life circumstances. Consider reflecting on your feelings toward your in-laws and whether there are unresolved tensions that need to be addressed.
