Is it normal that this could be true?

That's a very interesting (although unlikely) scenario; have you ever considered making it into a short story, perhaps? When I was a kid, I thought God was watching us on TV and in order to see what was happening in other parts of the world, he would just change the channel. Prayers would come to him like commercials, trying to convince him to grant one.

What kind of commercials do you think these people see? And is hentai the default pornography in their world, while 3D porn is considered like a niche thing?

unrelated, but when I was a kid, my bedroom was above the living room and the tv was directly below my bed and I used to think there was a family of tiny people living under my bed.

Cartoons or anime characters are 100% fictional. They cannot see, hear, feel, think or even take a shit.
You seem way out of touch with reality, and a bit of therapy might be helpful.

sometimes lol

No, they are just animations got directed, and no They have no brains.

Um, no!

The characters are only as real as you make them
