Here’s my thread from a couple of years ago about sleeping with your mobile phone in the bed.
Temperature is anything comfortable. I’ve got a friend who has stayed over a few times but he puts the apartment into absolute deep freeze. Drives me crazy and I end up having to put on a hoodie.
I have to wear some clothes to sleep in, maybe it’s all the years of having roommates or family that didn’t respect privacy.
I prefer flannel sheets and usually use them mid-September until May.
I will always listen or watch something before bedtime. I don’t have a TV in the bedroom because I have the iPad. Occasionally I’ll steam music and read before bed as well.
