Dreams involving fire often symbolize transformation, passion, or even the potential for danger. In your dream, the imagery of your oldest child laying with his feet in a fire pit while insisting he is okay suggests a feeling of helplessness or concern for someone you care about, possibly highlighting your fears about their well-being or choices.

The act of your child not responding to your pleas may reflect a sense of frustration or powerlessness in a situation in your waking life—perhaps you feel that you are unable to protect someone close to you or that they are ignoring your advice. The melting imagery could symbolize a gradual loss or deterioration of something important, whether it's a relationship, a situation, or their well-being.

Consider reflecting on your current relationship with your child or any worries you may have about their choices or safety. This dream might be your subconscious urging you to communicate your concerns more openly or to take action in a way that feels appropriate to you. It could also be a call for you to assess how much influence you have and what you can do to support them without overstepping boundaries.
