Aura movement

Q: Hi, I recently saw an outline of someone's inner aura which was a whitish colour.

When they moved their head it took a few seconds for the aura to catch-up, is this normal? Is there any explanation for this?

Eva's Response: It's just the way energy works. Think of it as a gas surrounding the body. Sometimes your body will move at a faster rate than that gas, and it will take a few seconds for the gas to catch up.

Same thing as when someone walks past you, your auras mix with each other for a brief second before catching back up to their owners. I see it all the time, it's completely normal.
