Is anyone else afraid of people not being who we think they are?

This is something I’ve been dwelling on for a long time. I was afraid of my parents one time, and that thought sort of struck me: how would you know if your family aren’t actually yours, if they’re not who they say they are, and in fact are just actors or machines or something like that.<br><br>Pretty weird thought at the time, but then you get thinking about it, and it’s actually pretty deep. We literally do not know who anyone is, and we’re all pretending to be who we are. We don’t know who anyone really is, and we really don’t know who they pretend to be.<br><br>You could say the same about anything you know in life. Nothing in life is what it seems, and we don’t know anything about the world we live in except from the fact that we live in it. We don’t know why we’re here, where we’re going, or how we got here. And we don’t know anything about each other except for the fact that we’re all here.<br><br>Has anyone else thought about this? Or am I just some sort of anomaly?
