But looking at the whole song instead of one line, it makes sense that
it's referring to his life in whole.
   My interpretation is that the song is directed to all the newspaper
writers and review writers and paparazzi that are constantly poking into his
private life and writing about it, and how he's laughing at them all for it.
Like how obsessed they are with what he's doing when he's not onstage, and
writing lies about him and things that they really have no business writing
about.
   i.e. The constant reviews that Creed is a Christian band... when, if you
simply looked at the words to the songs, and to what they (the band) have
actually said, you would know that it's wrong.  Or the constant comparisons
to Pearl Jam, when it's obvious that they are nothing like PJ, both in sound
and lyrics.
   It's like the song makes reference to writers (or people) who talk, but
don't show themselves (hide in shadows).  And he's laughing at the people
who are now obsessed with his personal life (I laugh aloud 'cause my life
has gotten inside someone else's mind).  The chorus, to me, seems to reflect
his anger about people printing lies without actually looking at the facts
(see above) and passing it off for truth in hopes of damaging some of the
fame and popularity that the band has worked hard for (At least look at me
when you shoot a bullet through my head).  The last verse, to me, seems to
be like "print a good real story about me, and I'll appreciate it forever,
but why do you print all this hatred for me and my band?"
   I don't know... that's just my interpretation of the song... and I find
it very hard to find biblical reference or connection to it that Paul is
referring to.
   At times, some have to admit that not every Creed song has something to
do with a religion, or a book, and I think that this might be one of those
songs.
   But that's just my opinion.
