Is it normal to feel like a stranger in my own body?

Sometimes when I look at myself in a mirror, see and/or hear myself in a video, or even think think about it long enough, I get this weird feeling that I’m not who I am. For example, when I look in the mirror, I feel like I’m staring at a stranger, and that I’m in their body, and not my own. I’ll sometimes not even be able to recognize my own parents as my parents. I still know that they’re important to me, but they’ll seem like strangers to me.
