While investigating around, I found a somewhat strange case of pareidolia in which, according to https://www.infobae.com/2006/09/11/275664-un-billete-us20-muestra-torres-gemelas-llamas/?outputType=amp-type and https://lasvegassun.com/news/2002/jul/22/burning-pentagon-wtc-spotted-on-20-spot/ There is a way to fold the 20$ bills (N#201837 and N#203921 ) to make them look like the Twin Towers were on fire from the tragic 9/11 accident.
According to https://www.instructables.com/How-to-make-a-20-dollar-bill-turn-into-the-twin-to/ the steps are:
Step 1: First Fold
First you need to make well this is what I call it a hot dog fold.
Step 2: The Next Fold
Next you need to make the fold that I did in this picture.
Step 3: Your Now Allmost Done
Now you just need to make the same fold that I did in the last picture only you need to make the fold on the left side instead of on the right side.
Obviously, this happens thanks to pareidolia, since the American Government or the Federal Reserve Bank were not going to put a hidden message in the form of an image of the 9/11 attack, or maybe they were, depending on the person who is reading this message.
