Theory: They are visiting you.
Thank you for best answer.
I wish I could dream of my lost loved ones...Maybe whats happening is the people you dream of is trying to get you to relate to their loved ones still living? Like the lady "she was singing to her dad" You don't remember the song "but she said the song is to tell him how much she loves him" Maybe this is her way of reaching out to her Dad.
I find that interesting, do you know them? what are they doing/saying?
