Well, he might be talking about rejoining Kalona and destroying Stevie Rae and Zoey's gang. Or Kramisha could also have given him one of her wierd poems again. Maybe Neferet compelled him to think crap so that Aphrodite is confused. Or even worse, Rephaim could have been dreaming about his death and the destruction of te world, under Neferet's influence, of course. Please don't mind if my answer is just oh so damn long and my answers might be very very wrong. I seriously haven't read the book yet. Sorry if it craps up your other possibly right answers. Thank you for taking the time to read my answer. :)
