DE has explained it - You have a special bond with the frame you choose for The Second Dream. As it is the frame you have bonded with the most, it becomes capable of limited actions to protect the Operator. Nothing as complicated as combat or movement that requires balancing, but using brute strength to rip a piece of a Sentient Assassin apart is possible.

Or for people more inclined to lorecraft - you have left a Somatic Resonance within the Warframe you have possessed most thoroughly, resulting in an impression of your conciousness being left within the Warframe. The Resonance was sufficiently powerful to perform very limited forms of self defence against your greatest enemies - Sentients and the Stalker.
