DH and I have seperate bedrooms - he snores and it's worked well for us for some 15 years or so. He does night shift, every third week, and finishes at 6.00am. He gets in at around 6.20-6.30am, and watches TV for a bit, has a hot chocolate, and then goes to bed around 7.30am. I tend to get up around 8.30am to 9am (I work from home.)
Anyway, he was on nights last week, and came in at 6.20am. I got up for a pee at 6.55am, then went back to bed for a bit as I was tired and needed another couple of hours. (I had worked til midnight the night before!)
15 minutes after I went back to bed - 15 minutes after! DH knocks on my fucking door, and comes in and said 'birdsong. BIRDSONG, are you getting up? I heard you up about 5 minutes ago and thought you were getting up.' It was 15 minutes later, not 5! And I had gone back to sleep!
He woke me out of my slumber and I couldn't get back to sleep. It made me tired and fatigued all day. I could have lamped him. I said 'no I am not getting up!' and turned my back.
'Oh well see you later then' he said. Then he continued... 'oh by the way, I just thought I'd let you know Steve at work is up for a disciplinary next week for what happened last week.' I was seething. Not only did he wake me, when it was only 7am, and he must have known I had gone back to bed, but also, he tried to engage in conversation with me. I ignored him, and he said 'talk to yourself eh? Never mind!' And he slammed the door!
When he got up at 4pm he had a face like thunder. He was still pissy that I had ignored him. I said 'tell you what, tomorrow, when you get up for a pee at lunchtime, I will wait 15 minutes and then open the door and start talking to you! Then slam the door when you ignore me because I have woken you from your sleep.' Idiot! 
tr;dr. YABVU @Autieangel Waking someone for no reason is a shitty thing to do. I would have been fuming if I had been your husband!
