Emma didn't know where she was. "Hello?" she called out. The place that she was in just looked like a big empty white space. What was she doing here? How did she get here?

"Emma?" a voice called.

Emma turned to the voice hopefully. She would know that voice anywhere. "Regina?"

Regina appeared out of nowhere, walking towards Emma. "Where are we? What are we doing here?"

"I don't know," Emma said. "I'll find a way to get us out though." She held out her hand for Regina to take, knowing that the touch would sooth them both.

Regina reached out her hand to grab Emma's, but was stopped by an invisible wall. "What is this?" she asked, pushing against the barrier.

Emma quickly walked towards her, but found that she couldn't get through the barrier either. "I can't get to you!"

"Choose," a voice said from behind Emma.

Emma spun around to face the voice, but saw no one. Instead, she saw three different tables set up, each with a heart on it. All three hearts were alive and beating.

"Choose what?" Emma asked.

"Which one to destroy," the voice said. "Pick up a heart and crush it."

"Whose hearts are these?" Emma asked.

"One is your love's," the voice said. "The other two are not important."

"But they belong to people?" Emma asked, looking down in dread at the beating hearts. What was she going to do?

"Yes," the voice said. "They belong to people. But you must choose which one to destroy."

"How do I know which one is Regina's?" Emma asked. They all looked the exact same!

"You don't," the voice said. "You have thirty seconds. Choose."

"I can't just choose who gets to live or die!" Emma exclaimed. "That's not my job."

"Emma?" Regina called. "What's going on? Is everything okay?"

"Choose," the voice commanded. "Or I will choose for you."

"No wait," Emma said frantically, scanning the hearts in front of her. Shouldn't Regina's heart have some darkness with it? She was the Evil Queen for quite a long time.

"Choose!" the voice boomed, causing Emma to shake in fear.

Emma mentally screamed before grabbing the heart in the middle and crushing it. She thought that everything was fine. And then she heard the sickening thud behind her.

"Regina!" Emma screamed, bolting upright in bed. She looked around at her surroundings, realizing quickly that she wasn't staying with her girlfriend tonight, but her parents.

"Emma?" Snow called up groggily. "Is everything okay?"

Emma went to answer, but found that she couldn't. Where was Regina? Was she okay? Had Emma really killed her? Maybe her dream hadn't been a dream at all, but a memory that she had tried hard to forget.

"David, she's not answering," Snow said. Worry laced her voice, but Emma found that she didn't care. She needed to see Regina.

Throwing off the covers, Emma quickly got out of bed and practically ran down from the loft. "Where are you going?" Snow asked, grabbing Emma's arm. "It's two in the morning."

"I need to see Regina," Emma said, panting harshly. She still hadn't managed to catch her breath from the nightmare.

"Why?" Snow asked. "She's probably sleeping, like you should be. Let's just go back to bed-"

"No," Emma interrupted, pulling away from her. "I have to see her right now and make sure that nothing bad happened to her. Right now."

"Okay," Snow said soothingly. "Why don't you go upstairs, and I'll call her to come over. Would that be fine?"

Emma knew that she was being talked to like a little kid, but she didn't care. She nodded and went back up to the loft, sitting on the edge of her bed. She needed to be ready for when Regina showed up.

She heard the sound of Snow's voice downstairs, and caught a couple words like "nightmare" and "emergency". A couple seconds later, Regina appeared in Emma's room, pajamas and all.

Emma stood up quickly and ran to her, nearly pushing her over with the force of her hug. "You're alive. You're fine. Thank goodness, you're okay."

Regina quickly got over her shock and wrapped her arms around Emma, rubbing her hand soothingly up and down Emma's back. "That's right. I'm fine, and I'm here."

Emma relaxed in Regina's embrace, listening just to the sound of her heart beating. If her heart was beating, that had to mean she was alive.

Heart. Emma had crushed Regina's heart and had killed her. "No," Emma mumbled. "It was just a dream. It was just a dream."

Regina guided Emma gently over to her bed, sitting them both down slowly. "Did you have a nightmare?" she asked.

Emma just nodded. Regina kissed the top of her head and continued her soothing movements until Emma began to relax. Feeling her relax, Regina went to pull away.

"No, no, no, no," Emma whimpered, clinging tighter to her. "Don't let go. I need to hear your heart beating. Because if it's in your chest, that means that it's safe."

"This is about my heart?" Regina asked.

Emma nodded. "I was in this big room, and you were blocked off from me. And I had to choose a heart to crush, and I was panicking, and I accidentally chose yours and you died. I killed you. I can't believe that I killed you."

Regina shushed her, rocking them back and forth. "You didn't kill me. I'm right here, and I'm fine. It was just a nightmare."

"I killed you," Emma whispered.

"No you didn't," Regina said. "I'm right here, holding you. My heart is in my chest and beating, and everything is fine. Go back to sleep."

Emma forced her breathing to even out, giving the impression that she had fallen asleep. Once Regina was satisfied, she laid Emma gently onto her bed. She kissed Emma's forehead before leaving the loft and heading downstairs.

Once she had left, Emma opened her eyes. There was no way that she was going to sleep again. Not when she had just killed Regina.

See you tomorrow! Mwahahaha :D
