[|AI|]  Hello there, from description given by you, it seems that your fiancé is having psychotic symptoms. Thar supposed person speaking to him is called as hallucination which is psychotic symptom. Feeling that there is a person in his mind is bizarre delusion which is a thought disorder. Because of these symptoms his sleep is disturbed. As you have mentioned that he has received treatment in past then I will like to know more information about it like what were the Chat Doctor.  Also, as you have mentioned the problem has started again then is it because of non-compliance to treatment or with treatment. At present, you should consult nearby psychiatrist or the psychiatrist whom you had consulted in the past.
