Dreams can often reflect our subconscious thoughts, feelings, and experiences. In your dream, walking in a sandy area may symbolize feelings of being lost or uncertain, as sand can represent instability. The "big hole" you encountered might suggest obstacles or challenges you are facing in your waking life that you are trying to navigate or overcome.

The act of entering another house can symbolize exploring new aspects of yourself or your life. Houses in dreams often represent the self or different facets of your personality. The presence of three people could suggest collaboration or support from others in your life, or they might represent different parts of yourself.

Receiving meat to eat may indicate nourishment or fulfillment. Meat can symbolize strength, sustenance, or the need for physical or emotional nourishment. It might suggest that you are seeking or receiving support or resources to help you on your journey.

Overall, this dream could reflect your current challenges, the support you have around you, and your need for nourishment—both physically and emotionally. Consider what is happening in your life right now and how these symbols might relate to your experiences.
