You talk in your sleep.
Not any more but I used to until my late teens.
You walk in your sleep.
Your SO can fall asleep easily.
Your SO sleeps on his back but you can't.
Your SO snores.
"Dogs teach us a lot of things, but none more important than to love unconditionally." ~ Unknown
Your SO sleeps closer to the bedroom door.
Your SO often falls asleep watching television.
You will forgive me if I close down for the evening?
