I think what I would rather see is that Tony has the extremis virus and is still trying to adjust to this new technology which connects his thoughts to his armor. So, I feel like during sleep he would still continue to control the suit, on a subconscious level.
Also, to me I feel like the part where the suit is crouched over Tony and the part where the suit is crouched over Pepper in the bed could very well be part of the same scene, except that the part where the suit is crouched over Tony he is actually in this subconscious nightmare (where perhaps he does believe the armor has a life of it's own), meanwhile in the conscious world Pepper sees Tony is having a nightmare and tries to wake him as the Armor is more or less performing the thoughts that Tony is having in the nightmare, except not quite perfectly. We already know Tony at first has trouble adjusting to the virus and using the extremis armor, as was previously shown in the picture of the hall of armors with the broken glass and helmet knocked off, so to me this scenario makes the most sense.
Just my thoughts of course though.
I'd hate for the sentient/controlled armor scenes to be dream sequences --- that's lame, and even lamer to try to drum up hype for dream sequences in a trailer. It's bait 'n' switch.
No, M-2's theory makes the most sense to me now: Tony gets the Extremis tech from Killian, thinking it's the Next Big Thing; but unbeknownst to Stark, the Extremis armor can be remotely controlled by Mandarin. The "nightmare" sequence involves Mandarin powering up the Extremis armor to go wandering around and scout out Stark's mansion in the middle of the night, and when he spots Pepper there, he moves the armor in for a closer look....
But I still think the Sentient Armor angle can be worked in, as that might be Stark's initial reaction to the situation --- he thinks the tech is so advanced that it's become self-aware, when in actuality it's simply being manipulated from afar by Mandarin.
