I would be happy to help assist you in understanding your dreams. Death in dreams can be symbolic. It can relate to how your husband is treating you. Since you are getting the impression of him trying to kill In your dream. Perhaps in real life his actions and motives are causing you to die emotionally and spiritually. How he is choosing to act or think towards you is causing you to loose yourself, to loose your connection to him emotionally and physically. Drowning in dreams can be showing a lot of emotions having to work through, as though you feel as if you are drowning in real life. It seems your husband is not handling your marriage or situation with you very well as he is choosing to "shut you up or suffocate you" instead of communicating properly and showing love. This is taking a toll on you. If you have anymore questions please do feel free to ask.
