I can't tell you how many times I've walked up to a bed, with another one right next to it, and slept there only to wake up to my follower standing by my feet. Did you sleep? Did you just stand there all night, Paranormal Activity style?

I understand that this would be complicated to detect if you had a script running all the time, and would cause performance issues. So what about a script that only runs when you activate a bed? Have it check to see if you have a follower (easy) then find a nearby unowned bed with, say 20 feet (easy?) and then sleep them in it (???).

When I wake up, I would so much prefer to find my follower still sleeping on a bed nearby and have to wake them up, then for them to be up and raring to go already. This problem is even compounded in my home, where there's a spare bedroom that nobody uses. Why is that bed there? And why, if nobody that lives in my house is going to sleep in it, can't I?

This happens a lot in dungeons too. I clear out a certain section, then bed down in a roll for a while. There are usually 2 or 3 bedrolls in a spot, sometimes I've seen quite a few of them. Follower never does sleep in any of them. It's not game breaking, but it's a little creepy. It would just make for a nice touch.

Thanks to you, I can never sleep in Breezehome ever again.

Your character doesn't sleep either. He/she just stand there looking at the bed for hours.

You just ruined my life.

When I accepted Lydia as a thane there were certain... expectations that would be required of her to remain in my "service". I won't go into detail but waking up before me and making breakfast was one of the most important.

Ask them to do something for you. Then activate a bed, it will say sleep on bed and they will do it. Doing anything else will wake them up though.
