Lily Evans, the one that existed in Severus' dreams was sitting by the lake, smiling, wind blowing her hair into her face, in the way of her eyes. She spotted Severus Snape, also in dream form, smiling at Lily. She got up and ran to Severus, smiling. "Hey, Sev!"

Severus was accustomed to seeing Lily in his dreams, but very unaccustomed to her being the first to speak, let alone the first to greet him. It made him feel that there was something slightly different going on here, like they were sharing a dream.
He tried to think about what he had been doing before he found himself dreaming. He had always been a lucid dreamer which was useful for a Legimens, but did give him the rather annoying inabilty to escape in his dreams. Suddenly he remembered the smoky potions class and testing their sleeping droughts. There was an old witch's tale that went "If love untold 'twixt friends there be, in potioned dreams are they sure to meet". But surely it wasn't true... Surely it was just a story.
Well, there was only one way to find out.
"Hi Lily," he said, giving her a hug. "What are doing out here all on your own?

"I was just put picking flowers and getting ready for OWLs" Lily replied, smiling. What's happening? Lily's unconscious mind pondered. It's like this is real. Almost as if we both are dreaming this same dream. This is the first time I have dreampt of Severus without Potter, so what could this mean? Is fate trying to tell me something I am too blind to see? Or am I just dreaming and is fate a lie?
"I like it here." Lily remarked, smiling. "It's peaceful. Beautuful. Almost as if nothing could harm me as long as I'm amoung the Lilys."

Severus smiled and looked over at the small patch of wildflowers. "Almost as beautiful as you," he murmured before he realised what he was saying. He hoped she hadn't heard.

"What?" Lily asked. I could have swarn he called me beautiful..

"Oh... I, er..." Severus realised he wasn't helping himself at all so he finished, "nothing."
He knew it was a dream, but he didn't know if Lily knew that he knew it was a dream. And after his disaster of trying to admit how he felt to her the other day, he couldn't bring himself to face going through it again.

"Listen. Sev. About what you said the other day.." Lily started. Should I tell him? This is a dream, right? Since It's a dream, I can do whatever I want, whatsoever without harming anything.

"Yeah?" Said Severus, expecting Lily to give some explanation about why she had suddenly blurted out that she had feelings for Potter. "You didn't seem so happy.

"Wasn't it you that said you'd support me? Always?" Lily asked, tilting her head.

"I did," he sighed, staring intently at one of the lilies, "but please understand, it's difficult for me this time. You know Potter and I hate each other. And the fact that I..."
Severus stopped. He was about to say that he was in love with her. Although he knew this was all a dream and could easily be forgotten, he didn't know how much Lily would take away from it. He didn't want to risk anything.

"I know.. James kept on interrupting me at potions earlier today. I'm sure you saw.." Lily remarked, sitting down. "And the fact that you...?" She asked.
He loves you, Lily. Not as a friend. You know that very well.

Severus took her hand.
"Lily, the other day when I said I love you... I meant that I'm... I'm in love with you."
It's just a dream.. It's just a dream... Lily told herself.
Lily placed her other hand on top of Severus', smiling. "I know. I just.. Didn't know what to say.."

"Say you feel the same," said Severus with a new boldness, his jet-black eyes meeting her emerald ones.

"I-I do." She said, looking down. "This is all a dream, Sev. You know that, right?" She said, sighing.

"Even if we could only ever exist in dreams, this moment is worth it."
He lowered his head slowly, only just grazing her lips with his, waiting for her to make the next step.

"If it is all we'll ever be, I'm okay with it. The stereotypes of you being a Slytherin and I a Gryffindor are much too heavy." She admitted, looking around, pausing. "Sev.. I've never kissed anyone." She admitted.

"Neither have I," Severus replied. "Seems fitting though."
Severus had never felt such immeasurable joy and sadness at the same time. He was completely elated that Lily did feel the same after all, but at the same time crushed because he knew that this dream would have to last him forever.

"Are you okay?" Lily asked, tenderly. "You don't look good. I mean you look happy but- sad." Lily was concerned on behalf of Severus, that much was certain.

Severus looked at Lily. "I'm okay, Lily. Just- I guess, a bit confused. It's my emotions doing it. Not me." He said, lifting his hands to indicate he was talking about himself.

Lily nodded, looking around. "Oh. Well, Sev.. I.. I don't know what to think. I really, honestly don't. I guess I just need to.." She paused, her voice tranforming from her voice to a young Lucius Malfoy's "get up! GET UP!"

Things went blurry for Severus, and he finally opened his eyes, Lucius Malfoy in his face. "Get up!"

It was just a dream. But he had to find Lily. And soon.
