Dreams about exploring large buildings, like a fancy hotel, often symbolize your quest for self-discovery or personal growth. The hotel may represent different aspects of your life, with the various rooms symbolizing different experiences or emotions.

The staircase you see can signify transitions or choices in your life. It may indicate that you are at a point where you need to make a decision or move to the next phase of your journey. The closed-off area and the gap suggest that there might be opportunities or aspects of yourself that are hidden or not easily accessible.

Crawling through the gap with your coat getting stuck could represent feelings of restriction or difficulty in accessing certain parts of your life or personality. It may also symbolize a fear of being exposed or caught in a situation where you feel vulnerable.

Hearing someone coming down the hall while you are trying to crawl through the gap might indicate anxiety or pressure you feel in your waking life. This could relate to concerns about being judged or not being able to meet expectations.

Overall, this dream suggests a desire to explore deeper aspects of yourself or your life, but also highlights some challenges or fears in doing so. Consider what areas in your life may feel restricted or hidden, and think about how you might navigate those feelings to move forward.
