Nightmare Support (слэш)

After the Battle of Hogwarts, the wards around the school reset, trapping everyone inside. When Harry goes to retrieve Snape's body from the boathouse, he finds him alive! He's brought back to the castle, and the find themselves spending every night side by side, staving off nightmares while the rest of the castle sleeps.
Spending so long trapped inside after such traumatic events, Harry grows restless and struggles with his lack of control. No one notices his suffering... except for his nighttime companion, who becomes much more as time goes on.
