Im a Sleepwalker Let Me

Tony's nights are plagued by nightmares, they have been since he was a kid. And ever since he was little, he always dealt with them by crawling into bed with his mother and letting himself feel protected.

Of course, he doesn't do this willingly; stumbling into other people's rooms and sleeping in their beds-- he sleepwalks.

So when the Avengers end up living together, Tony knows exactly what is going to happen and to make things even better, his nightmares are worse than ever. He is stressed out of his mind and is waiting anxiously for the day his team find out about his 'problem'

Too bad nobody told him that they would never think less of him for it.
