Yes, you're simply existing inside your head the whole time you're asleep, but you are still asleep (for what it's worth: you're existing inside your head the whole time you are awake, too). And, since all time is illusory, of course any dilation would be illusory too... why would that matter?
Extreme time dilation is likely not possible, or would be extremely difficult, for all the reasons we've already discussed, but I'm not sure this would be one of them. I'm also not sure you and Dutchraptor are giving your brains enough credit; they're capable of quite a bit.
