☆ Reminder to all self-shippers that if you're considered or have been told that you're unpleasant to sleep next to, your f/o doesn't care at all! In fact, they love your sleeping quirks and will always accommodate any sleeping disorders!
Whether you snore in your sleep, or require a sleeping aid to help your breathing, they don't mind whatsoever! And they also don't find it annoying! So long as you're safe and comfortable, it doesn't matter to them.
If you toss and turn a lot, or have really bad insomnia, your f/o understands, and rest assured it's okay! They don't mind it, and they aren't annoyed with you no matter how many videos you want to watch before you fall asleep, or how may times you need to flip your pillow to the cool side.
If you're a bit of a blanket stealer, trust and believe that they don't mind having a bit of a game of tug-of-war with the blankets! They might even just roll you up in a blanket of your own and hold you close, like a little sleepy caterpillar.
If you have chronic nightmares or night-terrors, your f/o will be by your side to help aid you when you awake from such frightening things. They'll hold you if you need that, they'll talk you out of your terrified state, they'll listen if you need to say anything about it. They don't mind doing that for you, because they will always want to be there to help you.
And of course, if you sleep talk or sleep walk? They're also okay with that too, they might even find it amusing if you're speaking nonsense in your sleep, and they'll make sure you get back into bed if you start walking around in the middle of the night.
