I wasn’t sure which ship meme you wanted so I’ll just do both (eventually). Here’s the sleeping one.

• Who is a night owl: Chili. He requires like 4 hours of sleep (and three cups of coffee in the morning) to function and usually stays up late working on projects for the Gym. Korrina, who works long hours as an Elite Four member, wants her husband to just come to bed already. 
• Who is a morning person: Also Chili. He pings awake at 6 am sharp everyday and is ready to go. Korrina needs at least half an hour to wake up and is often irritated by how chipper her husband is in the morning.
• Are they cuddlers: Yes. These two are very physically affectionate, and that includes in bed. They usually sleep spooning or face to face and entwined. 
• Who is the big spoon and who is the little spoon: They alternate, but it’s usually Chili just since he’s taller. He’s not taller by much though, so Korrina often is the big spoon as well. At the same time, she finds it cute how he clings on to her like a monkey so she lets him be the big spoon most of the time.
• What is their favourite sleeping position: As mentioned above, spooning or facing each other. As long as there’s physical contact they’re happy.
• Who steals all the blankets: Even though neither of them are particular blanket hogs or active sleepers, somehow, the blankets almost always end up on the floor by morning.
• What they wear to bed: Chili usually wears sweatpants and a tank-top or t-shirt, and Korrina usually wears the same but with shorts instead of sweats.
• Who likes seeing the other wearing their t-shirt: Korrina likes her husband in tank-tops since they show off his toned arms, but Chili is the one who thinks Korrina wearing his t-shirts to bed is the cutest.
• Who falls asleep mid-conversation: Korrina. She’s usually very tired by the time she’s ready to sleep so might just conk out mid-sentence. Chili is pretty good at regulating when he falls asleep so he always finds it hilarious when his wife does this.
• Who wakes up in the middle of the night with nightmares: Chili, simply because he’s had the more traumatic past. He doesn’t make a lot of noise when a nightmare wakes him up though, just opens his eyes and is awake. He doesn’t like to wake up Korrina when this happens since she needs her sleep, so if he can’t fall back asleep he’ll quietly get out of bed and go exercise or work on paperwork for the Gym, either until morning if it’s not far from the time he usually wakes up, or for an hour or so and then he tries to go back to sleep.
• Who accidentally punched the other in their sleep: Korrina. She has rollerblading dreams. Chili is the actual combat-trained one of the couple, but he’s also trained to not move in his sleep, so it’s usually him getting kicked in the shin by his wife while she’s dreaming of doing some rollerblading trick.
• Who can’t keep their hands to themself: Neither of them are particularly clingy in their sleep, but they both like to fall asleep in each other’s arms, if that counts. Otherwise, they usually stay in the same position, barring Korrina fidgeting or punching her husband in the eye or something.
