~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Do you have a anger issue with your partner that you are not dealing with?
Is there someting happening, or 'going on', in your life but you're not aware of all the details?
Are you feeling limited, repressed, or 'suffocated', anywhere in your waking life?
Is there something you need to face, or focus on, and take control of?

Alternatively, it could be that you were simply being crowded out of bed by your partner. If he was rolling over onto you, you may feel a bit frightened as well as angry, thus causing the dream.

Hope this helps, best wishes!
