I think its obvious. Your dad is dead thus he cant talk to you, yet you see him feel him. I think it means that there is a desire to connect/communicate with him, that his presence is very much important in your life. I would suggest that you make peace, accept your fathers destiny. It was his destiny to die and by loving him and respecting him it means also loving and respecting his death and his time to go. He is gone... the dreams are just part of a longing for a person who is not here anymore.... and that is okay> Death is natural. It compliements life, it doesnt complete it.
