A lot of strange things can occur in early recovery - physically, emotionally, mentally.... it's a turbulent time and the number of things, the ways they can manifest, the types and duration of symptoms are as varied and innumerable as the ways that we experienced addiction.
It's good you're seeing a therapist and psychiatrist. That is a positive step in addressing whatever is going on. If you're concerned physcially - consider getting a full physical and being honest with your doctor about your history so you can clear your mind of any significant concerns about your physical condition.
Apart from that, I suggest being patient.... having compassion for yourself... being open and honest with your therapist and working with the dreams by writing them down and simply allowing them to be and to speak to you.
It will ease up... things will smooth out.... if you continue to stay on path with sobriety and take the steps necessary to support your growth - this will prove to be a phase of your own evolution and one that helps you uncover a deeper way of living.
