They are NOT characters of their own. No matter how detailed their personality is displayed, they are not individuals. The Evil Nygma was only able to take over Nygma's body (stealing Kringle's corpse, etc.) because the Good Nygma and the Bad Nygma represented that Nygma was torn between the good and the bad side, with the evil side eventually taking over.

This is partially the same with the Oswald hallucination. It represents the feelings Nygma still has for Oswald and the guilt he feels for the murder. However, he leaves that behind as well, he even states that he will become his own man without the memory of Oswald hanging over him. Dropping the pills (and the hallucination vanishing) symbolizes exactly that.

Oswald, however, is not controling anything, he is not even cunning enough for that. He was even tricked by a hallucination of his own (Clayface acting as Elijah's ghost). As Ivy remarks, he has just woken up from his comatose state and he then immediately remembers what has happened and, being the character he is, intends to get revenge. I'm afraid I cannot see anything more to the situation, especially not Oswald using psychic powers to turn Nygma into... into what exactly?
