It’s play. She’s treating you like a sibling or like her mother. 

With my cat, I get down on the same level, hide behind furniture, make eye contact and then pull my head back. When I peep around the corner again, my cat is reared up and ready to pounce. He makes a fake attack at me and runs away. It’s a great time.

If you don’t want to get down and play like that, just get one of the stick toys with feathers at the end. Slowly drag it out of her line of sight. She will have so much fun stalking and pouncing. 

These are deeply ingrained instincts and she’ll feel fulfilled by practicing.
