Somnium - Sirius Black x reader

Part 4

No hand running through your hair, nobody's skin touching yours, you found yourself lying in bed, your eyes half closed as you faced the wall, aware of the fact you were dreaming again.
You reached your arm out backwards and tried to find him without looking, only to feel a soft and empty mattress behind you. Even though you had hoped the dreams would change previously, you missed the feeling of Sirius lying next to you today. Had the connection stopped, now that you knew it was really possible? Or had he decided not to come? Would he even have the choice, or was he just not sleeping right now?
And what had happened to him anyway? Lily had told you he wasn't feeling well. Was that something to be concerned about, or had he just eaten some spoiled pie?
Or were those dreams really just a construct of your mind; pieces of imagination, smoke and dust, neatly put together by your brain? There still was no real proof that Sirius had actually experienced this as well.

You sat up slowly and wished to be awake, or at least unaware of dreaming, until you looked around the room and saw him. Sirius was there and that fact alone made you feel better, even though he appeared to be uneasy. He was sat on the stone windowsill and seemed to be lost in thought, looking outside with a stern expression.
He didn't move or look at you when you got up and went over, still watched the treetops swaying outside and picked the skin around his fingernails absentmindedly.

Sirius jumped lightly when you laid your hand on his shoulder, apparently ripped out of his thoughts by your touch, and lifted his head to send you a smile. It was thin though and didn't reach his eyes like it usually did.

"Hey," you said quietly and pointed to the spot on the windowsill where his feet laid.

"Hey," he answered and tucked his legs up to make space for you to sit.

So you sat down on the opposing end and had to squeeze yourself into the narrow spot, because the space was far too small for two people to fit comfortably. You ended up sitting with your back against the stone wall, knees bent with one of your legs between Sirius', while one of his was stuck between yours, the inside of your calves touching.

You watched him for a moment, recognised how he avoided eye contact and how he acted as if the masonry beside you had suddenly become really interesting to watch.

"So," you said after a while. "What's going on?"

His eyes darted over to yours for a second, but quickly dodged again and drifted over to the window. "Nothing. 'M just in a bad mood I guess."

"You sure?" you asked and kept on watching his every move.

"Sure," he said and scratched the side of his neck, before he finally looked back at you. "So what did Bottrell tell you?"

Right. You had almost forgotten about the things your Divination teacher had taught you.

"Oh yeah. She said that it's indeed possible to have those kind of connected dreams. It's called Somnium Nexum and apparently it is quite common."

"Really?" he asked dryly.

"Yes. But people hardly ever recognise when it happens, so there's not much known about it yet. She said she needs volunteers to find out more, so I signed us up."

"What?" he gasped after a moment of silence, his eyes now staring at you so intensely, you almost felt them hammering against your skin.

"Well," you stated and cleared your throat. "She said she'd give us house points, so I thought it was a good idea."

"You told her? You must be kidding. Tell me you're kidding Y/N."

His legs were stiff around yours, tension seemingly rushing through his whole body, so you gave in and said: "Alright I'm kidding."
