Woah 😳 Why has this never crossed my mind? Anyone with extra info or links associated, please enlighten me 💚

I don't remember where I heard this, but I didn't go down any rabbit hole over it. I get it. I believe it. :(
I'm forgetting the guys' name who wears glasses? That talked about his time working on 51? So he kind of described what he saw between some doors at 51... and when I listened to it again more recently, I freaked myself out because it honestly sounded like he saw a child, or something child-size. But he wouldn't say that (and he wasn't asked). It was like, when you start to hear things differently - it stuck out to me the second time I heard it.
