When you are on a videocall do you also keep looking at your own thumbnail video?

When I speak, unless I'm sharing the screen I always keep looking at myself. It's kind of strange -- it clearly does not match a real-world conversation, but somehow I can't help it.

Edit: More context -- I'm wondering if others have it, if this is something that can be explained by some "brain" thing, and also how does it affect the conversation.
