Mirroring your movements and gestures

Respected,

I would like you to clarify me.
Mirroring your movements and gestures..... what does it mean?

Where and how can we use "Mirroring".

I suppose sentence structure is correct?

It would be better if you could give some some examples in this regard.

Please correct me If i am wrong, I appreciate your help.

Thanks in Advance.

Regards

Madhu
