The qiblah faces my bed and I share a room with my sister. Is it permissible for her to pray while I am sleeping on the bed?

I share a room with my sister and the room is very small. The qiblah faces my bed so when my sister prays she is facing me. My bed is not a floor bed, it haves a platform. Meaning when she prays I am not right next to her **but I am still in front of her.** Also sometimes she wakes up before me for fajr and I am sleeping. So, my question is should I move away whenever my sister prays? Or is it okay for her to pray while I am sitting or sleeping on my bed? ***Should she put a pillow or some type of barrier just to stay safe?***
