Hey, don't back down, your interpretation is just as valid as mine! I can see how lyrics like "I'm
about to find it out" might be interpreted as that the narrator is not
yet a ghost. I just didn't see anything in the lyrics to suggest that the song goes into flashback after the first few lines so since he is clearly already a ghost at the start I went for a sort of interim view, ie this person hasn't been a ghost for very long and is not yet used to the routine.
We need to remember two things:
1) It is a truth universally acknowledged that Maiden songs mean different things to different people, and
2) Unless/until Steve comes back to fill us in we won't know all the answers anyway.
In the meantime all interpretations are equally valid - and equally open to discussion
