Dreaming about cleaning your room can symbolize a desire for personal growth or a need to clear mental clutter in your life. The presence of the girl, who you believe may be your girlfriend, might represent feelings of support, partnership, or affection in your waking life. Her helping you clean suggests that you value her presence and assistance in your personal journey.

The tofu in the trash can could represent something that you perceive as wasted potential or an aspect of yourself that you feel is undesirable or needs to be discarded. Tofu is often associated with nourishment and health, so finding it dirty may indicate feelings of neglect regarding your own well-being or aspects of your life that require attention.

Consider reflecting on areas in your life where you might need to "clean up" or let go of things that no longer serve you. This could be related to relationships, habits, or emotional baggage. It might also be worth thinking about how you view support from others in your life and whether you feel comfortable accepting help when needed.
