I see them as three disjointed themes around your healing journey. Though first one is fairly direct and straight forward, and separate from the latter two, which are sort of connected.
Interpreting the Part I - Inside the Jail, is fairly simple - You are inside the survivor prison, and label of 'Survivor' that is stuck with you! The fear is of being humiliated if you step put of your survivor prison, and come out with your secret in public, as you already feel different and that people can spot you by your tag, even your license plate has some identification that separates you from the public! May be its time to get rid of your tag and step into the real world, outside the prison, you have remained a survivor for long, time to move on!
Keep a dream diary, and allow the interpretations to comes from the source, where the dreams originate from!
Part II - With the T inside the car - You have put your T in the drivers seat of your recovery journey, who is taking you head on into the past, so that you may collide with it, and that is what you may be fearing all this while - confronting the past or its fears! You want him to be careful and keep you safe instead, but then you can either be safe or heal.
Part III - Inside the hospital - Your T (Life) is wanting you to commit to a greater level to your healing, and making it is easy for you, but you are unwilling to let go of your comfort levels, - dogs.
Part IV - Penis dream - Fear of being emasculated, of your masculinity! But then you know that all you have to say is - NO!
