eli5 What is a liminal space?

I've googled it and I'm left more and more confused. It seems like its just empty rooms. Why does this make people feel uncomfortable. 
Do these images affect everyone?

“Liminal” means “transitional”. It’s space that you pass through without noticing like an alley or a hallway. Because it’s something that you normally don’t pay attention to, art that focuses on it can seem unsettling, taking something familiar and looking at it in a new way.
