Dreaming of being lost in a big building can symbolize feelings of confusion or being overwhelmed in your waking life. The building often represents your mind or your current situation, and feeling trapped inside it suggests that you might be grappling with complex emotions or decisions. The presence of people waiting on you could indicate a sense of responsibility or pressure you feel from others.

This dream may highlight your concerns about not meeting expectations, either your own or those of others. It might be helpful to reflect on areas in your life where you feel stuck or pressured and consider ways to address these feelings. Taking small steps toward clarity or resolving the issues that are weighing on you could help alleviate this sense of being lost.
