Therefore, he doesn't actually "stand" in the conventional sense. He mostly interacts with the living world through various supernatural means:
* Moving objects: He makes objects move, like dishes and a lamp.
* Communicating through others: He uses a psychic medium to communicate with his girlfriend Molly.
* Appearance: He occasionally appears to Molly in physical form, but she's the only one who can see him.
So, while he has a presence throughout the movie, it's not through physical movement or standing in the way we normally understand.
