To dream that you have swallowed something possibly indicates that you are holding back your feelings or words about something or someone. You may feel unable to openly express your anger or feelings of aggression about what has happened or has been done to you by another person.
Another possible alternative interpretation would be that you have been up until fairly recently unwilling to swallow your own pride long enough in order to make major progress with improving your relationship with this person, but have now made a significant positive breakthrough in this direction.
To see a snake or be bitten by one in your dream, signifies hidden fears and worries that are threatening you. It's black colour only emphasises how serious you see this threat to be to your own sense of inner peace.
By biting the black snake back and swallowing it whole in your dream, you are effectively neutralising or rendering harmless the negative effects these fears and worries could potentially have on your ability to live your life as you best see fit to do so.
To eat them before they are allowed to eat at you, or spoil your life?
Keep up the good work as this type of dream generally indicates that you are really making wonderful progress towards overcoming your fears and worries, and are learning to express your justifiable anger in more constructive ways.
