Dreams involving sensations in the body, such as a rattling in your ear, often symbolize a need to listen more closely to your surroundings or to your inner thoughts. The ear can represent communication and the way you receive messages from the world.

Pulling out a large honeycomb may symbolize discovering something sweet or valuable within yourself or your life. Honey often represents abundance, joy, and nourishment, while the act of pulling it from your ear could indicate that you need to express or communicate something sweet or positive that you've been holding inside.

Your boyfriend eating the honeycomb could suggest a sharing or consumption of this newfound insight or happiness. It may also reflect your feelings about how those close to you engage with what you have to offer. His response that it's "really good" might indicate that he appreciates the sweetness in your life or the message you have to share.

Overall, this dream could be prompting you to pay attention to your inner voice, share your sweetness with others, and consider how your insights or creations are received by those around you. You might want to reflect on any recent experiences that have brought joy or abundance into your life and how you can express them further.
