Do merc item auras stack with player item auras

I have a zeal pally with dual dreams, If I give my merc a dream helm will the aura off that stack too to make a lvl 45 holy shock aura?

If so would my synergy's affect the merc's holy shock aura too?|||No the merc has lvl 15 aura 30 if 2 dreams as far as I'm aware|||Hartside is correct. Think of all the hammerdins that would use Pride over Insight if that was a possibility.
