Pat,
The second dream.
There are probably specific waking experiences this dream is addressing but again I believe it is a general observation about life.
You are reflecting on life and the past. There are regrets, but with acceptance {what can you to change the past?}. There are thoughts of your 'transition' but you have accepted it as a part of life. You have taken a candid approach to the issue of life and death but you are ready for or near the end. There may be specific regrets about bowing to the masculine {your husband} but you begrudgingly accepted that part of your life. Later life has proven full of threats with specific aspects {possibly to do with your children} more difficult to deal with. There may have been recent events that have been very 'injurious'. You have had to close your eyes to those aspects to avoid any feelings of hopelessness. You have learned to stay positive even when you are wounded by others.
I sense both dreams reflect a general attitude you have toward life. They would reflect your overall personality. The wedding part may be addressing specific experiences but would also be about your attitudes. At 70 you are at that stage of wise reflection {mid-life is about looking back and assessment} and having the personality you have a positive statement of how you have lived life. Taking life as it comes and rolling with the punches.
