I was playing with my friend and they had to g9 as I got into bed and closed the world. They were back on a few days later and I logged in. It was daytime in the Minecraft world so when I got in, I was in my bed at daytime! The weirdest thing was that I couldn’t get out of the bed until it was the next day. Here are the steps. 
1. Join someone’s Minecraft world, get In a bed,  and let them close it. 
2. Let them play till the next Minecraft day. 
3. Get back in and you’ll be in bed, un able to get out until the next day.
