The lady at you back might represent you female energy. We all have female and male energies. When you are working, leading, incharge it is you male energy. When you are resting, day deaming and relaxing its is you female energy. In this dream you female energy is giving you some support and doing so trying to create more balance in your life. Probaly you are working to hard and need the pamper of the female energy. Try to give that to yourself.
About your second dream I have seen several posted about your father´s resurection.
This time is him not realizing he is death. Many things about a person remain with us forever, their beliefs, dreams, ideas, business. Probably there is an aspect of his remainig energy you want to let go. Thats why you are telling him he is death.
Just some thoughts!
Good luck!
