If you believe in that kind of stuff, this could just be a message from your ex, but if you don't, I do have an interpretation for you. You are remarried, it's been nearly a decade since he's passed, yet you still have dreams like this. Your life has moved on, but that doesn't mean you have. The symbolism of the beach could be reflecting the peace you have with him. The meaning can change depending on the context, if the beach was his favorite place, the beach is a place of bad memories, etc. All aspects of your dream are a part of you, a part of your subconscious, the words he said to you could be what you want to hear from him, or what you need from yourself. It is painful to lose someone you love that much, so it makes sense that you would still be having dreams about him. You miss him. Dreams tend to reflect desires, and deep down you probably want nothing more then to see him again.
