Can we manifest things just by thinking positively about them and feeing good about them?

Where does this ridiculous idea that you can manifest money, or a parking spot, or whatever, just by thinking positively and feeling good thoughts come from?

Like, how on earth would “parking spot magically appears” be a result in the model? Does that actually happen for people who believe that it could?

C I want a parking spot
T parking spots are everywhere, they just open up to me as I drive near, I am so lucky, I am so good at manifesting parking spots!
F open and hopeful?
A drive around
R parking spot opens up like magic!

This seems absolutely ridiculous to me.
