Why do I get so dizzy and weak? I eat sleep walk... What's wrong with me!?
Call up your doctor.
Look up the symptoms of vertigo.
Do you have an inner ear infection, best to see a doctor and maybe a neurologist.
So many reasons...definitely see a professional.
Are you on medication? Sometimes meds can make you sleep walk, eat in your sleep or babble. (especially sleep meds like ambian).
Do more exercise
