Both are good, but if you go melee you get the most out of Dream with its PS, Distort Reality and maybe ToW.
With Mines, Seal and others this playstyle has so many PBAoE-like skills I like to call it the Allahu Akbar Build, and that is how you can play it.
Your survivability as int melee will come from Energy Armor. And if you still need more switch to energy-leeching shield.
