It’s just a fun and silly way to say she deeply admires Taylor Swift. What else could that mean?
I think it means that whenever she is done with work and stuff, and has a good bit of downtime, she will go into her Taylor Swift chamber where every surface is lovingly adorned with tastefully beautiful images of Taylor, where she will rest on a Taylor Swift pillow and listen to LPs of her music while watching videos of her interacting in social circles online.
