Dreams about large, forgotten hotel-style buildings often reflect feelings of exploration and self-discovery. The hotel can symbolize various aspects of your life, such as your experiences, memories, or even your emotional state. The fact that the building feels dated or forgotten might suggest that there are unresolved issues or aspects of your past that you are trying to come to terms with.

Exploring the back rooms may indicate a search for deeper understanding or hidden parts of yourself that you have yet to confront. The old conference rooms and hotel rooms might represent past experiences or relationships that still hold significance for you. Being chased in your dream could signify feelings of anxiety or pressure in your waking life, potentially linked to these unresolved issues.

The central river might symbolize the flow of emotions or life’s journey, suggesting that you are navigating through your feelings and experiences. It could represent the connection between your past and present, highlighting the importance of reflecting on where you've been to understand where you're headed.

To gain more clarity, consider what emotions arise during these dreams and if there are any current life situations that may relate to the themes of exploration, fear, or unresolved issues. Reflecting on these aspects could provide you with insights into your waking life and help you process any underlying feelings.
