Dreams about physical pain, especially involving the jaw and mouth, can be quite distressing and often symbolize feelings of being silenced or unable to express oneself. Your experience of the jaw locking and the intense pain may reflect a situation in your waking life where you feel restricted or unable to communicate effectively. It might also indicate anxiety or stress that you're struggling to articulate.

The sensation of spitting out bits of your tongue and blood could symbolize feelings of loss or the consequences of not being able to express your true thoughts and feelings. This could suggest that you are holding back emotions or ideas that are causing you internal turmoil.

The physical sensations you experienced in the dream, like the soreness of your tongue upon waking, indicate how deeply this dream impacted you. It may be beneficial to explore any current situations or relationships where you feel you are not being heard or understood. Reflecting on these feelings could help you find a way to express yourself more freely in your waking life.

Consider journaling about your emotions or discussing your feelings with someone you trust. This could help alleviate some of the pressures that your dream has brought to the surface.
