Hello, and this is my idea. Maybe, you can make a connection with camera. So, when you will touch a button to start to record your moves while you sleeping, camera will also start to record the video. After you will woke up, you can watch this video. Maybe, it’ll be interesting and more accurately to record sleeping poses 
P.S. I’m really sorry for my English skills :c
