This was the last of the headcanons I was asked to do, it took a while to write, but I think it turned out alright. Let me know what you guys think by reviewing. *hint hint* ;-)
The Nightmares
The Doctor may appear all bubbly and jolly all the time, when people are watching that is. If you look really closely, you can see that this is a front. Not all the time mind you, just sadly most of the time. Then next time you see him, just look into his eyes, you'll see what I mean, all the depth in his eyes, the sadness. The eyes that have seen everything, but nothing at all, and he pushes it away, all of it. Tries to anyway, sometimes it all comes back to him when he least expects it.
Running down a corridor, being chased by a carnivorous lizard, his converse crashing down on the metal grating on the ship, when he's reminded of something very similar, but just with a different companion. You can even see it happen sometimes, see the excitement in his eyes die into embers and his grip on my hand loosen just a little, then tighten even more than before. His smile slowly fading, but being replaced with a smile to try and hide the pain. Not to mention the many nightmares.
Waking up beside a Time Lord who is stuck in nightmares and memories is one of the worst things I've seen, that, and when I thought I was never going to see my mum or Mickey again. The was he twists and turns in the sheets is heartbreaking, the sadness and pain clearly shown on his face, gut wrenching, but not being allowed to wake him up, the worst. As The Doctor said, "don't wake me up. Not when I'm having a dream or a nightmare. Never, I might not know it's you Rose, and I might hurt you, and I don't want to." That was when he kissed me, and brought me to bed with him for the first time. He doesn't seem to have the nightmares as often now, with me sleeping with him. That's good. That's very good, I don't like seeing him like that, it breaks my heart twice over to see him like that.
