Women with an intense stare followed me barefoot from keycenter.

Hi, I’ve started a new job in an office inside key center. Yesterday, when I was coming out of the building, a perfectly looking middle age women who was barefoot started following me with a very intense stare. She followed me outside to the crossing and somehow I managed to get out of her sight in the crowd.

She looked perfectly calm but had an extremely intense stare. She had headphones on and seems to be chanting something.

Anyone know who was she? I’m extremely terrified to go to office tomorrow.
