Nightmares || Merlin fanfic

For my OTP that rose, crashed, and burned in the space of 40 minutes.

After Freya's death, Merlin is struggling under the weight of his guilt and grief, unable to move on. The thought of her steals into his head, invading his dreams, and hijacking his every thought. The world around him continues to turn, his friends oblivious as ever. But does Arthur see more than Merlin gives him credit for?
