Some Ideas/Inspiration
While I’m sorting trough things, I thought it might be interesting to share my thoughts on the theme!
Maybe it sparks an idea in you 
- One room as place of refuge
- your shelter from the outer world
- the things in your room tell more about the person who lives/lived here (Firewatch did that really good)
- window could play with desire to explore the outer world
- yet you are confined to this place, find out who lived here or more about yourself
- could be linked to an abadoned/ruins setting
