There are many symbols of death in this dream. It sounds like the dream is telling you that something in your life is changing (something ending so that something new can begin.)
Ricky's old house might refer to how your relationship was in the past.
Was the person you were hiding from the person who came in the front door? Maybe that person represents something that you are trying to avoid or ignore.
Looking into another room could mean that you are looking for different ways to approach a situation. The dead man is a sign that something has ended. The babies mean that you tried to start something new, but it didn't work (they died).
Why do you think Ricky would say "I don't care" when Bow threatened to kill you? Is it possible that you feel that Ricky doesn't care about you enough?
The fact that he had a white beard like Gandalf could mean that he represents someone who is wise/a teacher - he is letting you know the truth. Does the friend his face was shaped like mean anything to you?
The oversized houses and couches could mean that you are feeling overwhelmed.
I noticed the colour white comes up a lot in your dream.
White can stand for hope, innocence and purity, but it can also stand for death and desolation.
A
tiger can represent strenth, anger and revenge. Is there any reason you would associate Bow with a tiger?
A tiger can also kill you, so it could also symbolize death in your dream.
