Dreaming of exploring a large, fancy hotel often symbolizes a journey of self-discovery or a desire for luxury and comfort in your life. Hotels can represent transitional spaces, indicating that you may be in a phase of change or introspection.

The empty halls might suggest feelings of isolation or a search for solitude in your life. The staircase you encounter often symbolizes progression or ascension, indicating that you may be seeking personal growth or advancement in some area.

The gap in the wall represents hidden opportunities or aspects of yourself that you might not fully understand or have yet to explore. Crawling through the gap can signify a desire to delve deeper into these hidden parts of yourself, but getting stuck suggests feelings of anxiety or obstacles in your pursuit of self-discovery.

Hearing someone approaching as you try to escape may point to fears of judgment or confrontation with others regarding your personal journey. It might suggest that you feel pressured to conform or to hide certain parts of yourself.

Overall, this dream could be reflecting your quest for understanding and growth while navigating feelings of vulnerability or pressure from external sources. Consider what areas of your life require more exploration or where you feel stuck, and think about how you can address these feelings in your waking life.
