Hi, I record/interpret dreams often. I'm not saying this is for certain what it is (since I don't know the full context of your dream). But just based on what you said, you broke contracts on yourself and bloodline. The dream was you coughing up blood, which to me signifies the expelling of those contracts and that you have been cleansed? According to the bible our life is in the blood, so maybe this is showing a renewing/cleansing of your life(from the contracts being broken)? Again, there are other aspects that could affect the interpretation, I think it's important how you were feeling/your reaction when that was happening in your dream. I hope that helps a bit maybe. I totally understand being very careful about sharing your dreams and messages with others, I'm the same.
