It's almost meta with a deliberately lying narrator, because they'd have no reason to lie if they weren't aware someone was listening ... so they're in that sense breaking the fourth wall when they do so.
Nah, I lie to myself all the time. But I have a reason, usually. I want to eat that cake I'm not supposed to.
