I separate by the mechanics at play: do supernatural things exist in places they do not exist in reality (humans doing telekinesis, mind reading for example... Or outright magic like the force)? If yes, it's likely fantasy.
Where does subspace fall on this line? Stargates? The TARDIS?
Sometimes the science is magical. The line is pretty fuzzy
