Is it normal that i like to record myself?

I've noticed there are times, especially when my anxiety is acting up, I like to record myself and go over the material. Like SnapChat, I record myself and watch over the video a few times. Observing the way I speak and body language. There are times I have full conversations with myself. I get embarrassed at times think other people are watching me. (only when I record in public)

So, think it's normal?
