This does not seem correct to me. And ghosts have nothing to do with it.
For example, I could be the only person in a room. I observe that in the room, there is a blue chair. Although there is only one observer (me), the phenomenon of the blue chair does not seem to be imaginary.
(Unless, of course, all of reality is imagined. But that is probably not what you meant to say.)
