Yes, I've done this. I did it a lot when I was younger, and now that I'm getting old, I find that I do it when I'm stressed or very excited.
Google "face-blindness" - you'll see that this is an actual thing, and that folks on the spectrum can have it to different degrees. It shows up in at least two ways: you might not recognize someone you have met before, or you think a stranger is someone you know, because of slight resemblances.
And don't feel too bad. You've heard of Richard Feynman, physics genius? He had it so bad, all his life, that there were times when he could only recognize people by their voices! People learned to announce themselves to him. So if you have it, even slightly, you're in pretty good company.
