Hufflepuff: Late night snacks. Sleeping with a pet in your room/on your bed. Making up those perfect conversation in your head that let’s be honest you’ll probably never say in real life. Trying to count sheep then getting distracted by wondering why it’s not counting iguanas or something (also applies for Ravenclaw tbh, sorry)
Ravenclaw: Procrastinating. Complaining about how late it is and how tired you are and then staying up at least 2 more hours. Trying to teach yourself to lucid dream but constantly falling asleep before you actually can. Calculating how much sleep you’ll get if you fall asleep right now
Gryffindor: Constantly waking up in the middle of the night to pull the covers you kicked off, back onto your body. Sneak out of your house with friends (not that I’ve done that cuz I’m pretty lame tbh). I think they’re pretty heavy sleepers tbh like once a Gryffindor is asleep it takes at least 10 alarms to wake them up
Slytherin: Cuddling with someone (surprise I bet you thought this was going in a different house), listening to music to fall asleep. Thinking back over everything you’ve done that day and cringe at the stupid things you’ve said. Heavy or light sleepers depending on how much sleep they know they’re gonna get, like when I know I’m only gonna get 3 hours I wake up on my first alarm, if I’m sleeping more than 8, someone literally has to shake me awake
