What are these lines everywhere?

Life, Supernatural

While continuing her European road trip, Zarya Li begins to notice multiple things around her, like glowing lines in the sky and a slight aura around every person she sees. Unsure of what is happening, she asks her family if they see these things but they have no idea what she is talking about. She also learns that the little shop where she had received her bracelet had been burned down and the shop owner was reported dead.
