Dreams about fire often symbolize strong emotions or passions, but they can also represent danger or feelings of being overwhelmed. In your dream, having a BBQ at a Japanese place might indicate a desire for enjoyment or a communal experience. The chef spraying oil and igniting a fire could symbolize a situation in your life that is becoming volatile or out of control.
Getting burned in the dream suggests that you may be feeling vulnerable or that your passions may be leading to negative consequences. It could also reflect feelings of anger or frustration about a situation where you feel you’ve been unfairly affected by someone else's actions.
Consider reflecting on areas in your waking life where you feel a lack of control or where your emotions might be running high. It might be helpful to think about ways to manage these feelings or situations constructively to avoid getting 'burned' in the future.
