The artistic key element of "Our sleep is more fragile than we are" is that the performances in the different rooms and their looped live videos are synchronized, resulting in choreographed moments of the exact same movement in all three video channels and the live performance, before their actions diverge again. 
In order to secure the synchrony for the piece an extended movement research and hyper choreographed directing was a vital part of the process. Additionally, the actress (Anna-Maria Hadorn) was equipped with an invisible in-ear headset that gave her precise performance directions almost every second she was moving around. She was required to perform a perfect playback of her own movements without any possibility of deviation.
