AN: Enjoy!

Wanda Maximoff had always been prone to nightmares. Even before the tragic deaths of her parents she had nightmares, she'd been a sensitive little soul, often sleeping fitfully.

Back then, Pietro would crawl into bed with her, and hold her until she settled.

Wanda's fitful sleep evolved into full blown night terrors after her parents died, and she often woke screaming. She knew this had made life more difficult for Pietro, who often struggled to quiet her to try and avoid punishment from their less pleasant foster parents, or keep them from being found by unsavoury characters when they were sleeping on the streets. He had never complained, though, and for a while, in their late teens, her night terrors became less frequent. There had been somewhat of a resurgence after the trauma of Hydra's experiments, but she'd managed to keep them mostly under control.

The night terrors had returned with a vengeance after Pietro's death. However, she was lucky, after moving into the Avengers compound, to have Vision to help her. And even after the civil war, after she'd had to escape the Raft and go on the run, he had helped her when he could.

Vision, it seemed, was the cure to her bad dreams. The reason that, strangely, a night terror had become linked with one of Wanda's most precious memories.. That of the first time she and Vision had made love.

When Wanda was with Vision, when he held her as she slept, her nightmares remained at bay, and on the increasingly rare occasions that she did have one, it was almost never a full-blown night terror. Wanda was grateful for this, as Billy, unfortunately, was a little psychic sponge, so if she had a nightmare, he usually would too.

Unfortunately, as they would soon learn, Billy's psychic sponge abilities didn't just pickup on his Mother.

One night, during their stay at the Avengers' compound, Vision held Wanda as she slept, as he did every night. The twins were sleeping top and tail in a port-a-cot beside the bed, which they always did when away from Home.

Billy suddenly woke with an anguished wail. Vision, while immediately leaping out of bed to tend to him, instinctively glanced over at Wanda. She didn't seem to be in any kind of distress, but she was waking up, roused by Billy's wail.

"What's wrong?" Wanda jumped up as Vision was scooping Billy into his arms. Tommy, also disturbed by his brother, whined plaintively at being woken, so Wanda picked him up as well.

"I don't know!" cried Vision, holding Billy close and trying to calm him. "I thought you must have had a nightmare."

"No, I.."

At that moment, Natasha burst in, pistol at the ready, but lowered it when she found no sign of danger.

"What's wrong?" She asked, over Billy's continuing wail.

"I think he must have had a bad dream.." Wanda replied. Suddenly, she noticed that Billy was clutching his arm, and her blood ran cold. "Nat, where does Bucky sleep?"

"Oh, he's up on the next floor. Steve thought it was stupid because there's plenty of spare rooms down here with the rest of us, but Bucky insisted because he didn't want to disturb us when.." Natasha had been confused by Wanda's question at first, but a look of horrible realisation suddenly dawned on her as she spoke. "When.. When he has nightmares."

Wanda hugged Tommy and set him back down in the cot, hoping he would be tired enough to simply go back to sleep once it was quiet, then bolted from the room, with Nat, and a very confused Vision, still clutching Billy, following close behind her.

Wanda bolted upstairs, since the elevators away from the main living floor were locked when the twins were visiting, heading the direction Nat showed her as she headed to Bucky's room.

"What's going.." Vision began, still confused, but his question was quickly answered by the screaming and thrashing on the other side of the door outside which they stopped.

"Bucky!" Wanda knocked quite furiously on the door. She knew the effect that nightmares could have on people, particularly knowing the ins and outs of Hydra experiments more than most. She was concerned for her friend as well as her son, while also slightly worried about infringing on his privacy.

"Barnes, wake up!" Natasha, however, had no such concerns, and when he didn't reply, immediately kicked the door open.

Bucky woke with a start, almost leaping right out of his bed. Looked around at the gathering at his door with wide, slightly frightened eyes.

"Wha.. What's going on?" His eyes widened further, panic growing. "Oh shit, what did I do? Did I hurt someone? I really thought they'd got all of that Hydra crap out of my.."

"It's alright" said Vision, bouncing Billy who was slowly calming now Bucky was awake. "You haven't hurt anyone."

"Definitely not" Wanda assured him. "It's just that, well, Billy can't entirely control his powers yet.. He's a bit like.. a little emotional antenna, I suppose, and sometimes he picks up on other people's nightmares.."

Bucky glanced at Billy, who was still whimpering in his Father's arms. A look of absolute horror spread over the former Winter Soldier's face. No child should ever have to witness the things he saw in his dreams.

"I am so sorry.." Before anyone could say another word, Bucky was hurriedly dressing, and packing a bag.

"What are you doing?" Natasha frowned.

"It's obvious, isn't it? It's not safe for the kids if I sleep here while they're visiting.." He slung the bag over his shoulder. "Tell Steve I'll be at a hotel or something. He'll worry."

"Bucky.. We really don't want you to.." Wanda tried, until he cut her off.

"It's for the best.. I really am sorry."

Try as they might, no-one could change Bucky's mind, and he took off into the night, borrowing one of Steve's motorcycles.

Wanda and Vision, now both comforting Billy as he finally drifted back to sleep, watched their friend leave with matching looks of concern.

This didn't feel right, and somehow, they would have to fix it.
