Dreams about houses often symbolize the self or aspects of your life, with different rooms representing different facets of your personality or experiences. The particular house you've described seems to carry significant meaning for you, given that it recurs throughout your life with a consistent layout.

The open space concept and high ceilings may reflect a desire for freedom, openness, and new possibilities in your life. The abundance of light from the big windows could symbolize clarity, optimism, and a positive outlook on your current or future situations.

The two connected living spaces could suggest a duality in your life—perhaps representing different aspects of your identity or contrasting feelings about your current circumstances. The first part of the house, being more modern and open, might symbolize your aspirations, ambitions, or a more dynamic phase of your life. In contrast, the second part with a cottage-style vibe may represent comfort, nostalgia, or a longing for simplicity and relaxation.

Your feelings of anxiety and excitement as you explore the house indicate a mix of apprehension and anticipation about what lies ahead. This could reflect your current life situation, where you are ready to take on new challenges or explore new opportunities but also feel uncertain about what those changes might bring.

Consider reflecting on what aspects of your life you are currently exploring or feeling anxious about. This dream may be encouraging you to embrace these feelings and view them as a natural part of growth and exploration.
