Nice strategy, but I’m not going to buy 10 bottles of shampoo, not that I would have anywhere to store them if I did.

If you feel crazy because you don’t fit in, it’s entirely possible you’re not the crazy one. It’s entirely possible a large portion of society is on another bender.

I found the book, “Extraordinary Popular Delusions and the Madness of Crowds” by Charles Mackay helpful.
It was first published in 1841, so it’s in the public domain and available online. I found my copy in a used bookstore for a $1.
Mackay documents many of the public manias that overtook society up to that point. He describes dozens of them and remember, his list stops in the mid-1800’s.
Being aware of this pattern helps me to realize that a large number of humans are highly illogical. It helps me to understand that yes, a large number of people can all go off the deep end. It’s not me, it’s them. Notably, I can’t do anything about it. All I can do is lie low and ride it out.
