This and the linked "you can't unsee article" are great example of how our perception is very far from a direct representation of the world, and instead is the end result of a complex processing happening inside our brain. Another example of the same effect (although here actually there _is_ no real message) can be heard in songs when listened to in reverse (for example see [1]). One lesson to learn might be: be wary of our brain recognizing patters, it tends to err on the side of seeing patterns when there are none. I would argue that religion and superstition are examples of this. [1] https://www.youtube.com/watch?v=mlvFkws9PYY https://www.youtube.com/watch?v=mlvFkws9PYY
