How can a dreamboard actually make your dreams come true?

For those who never tried this or never heard about it. A dreamboard basically is a huge piece of cardboard, canvas, paper material or a sheet of paper the size of a wall poster with magazine pictures you cut out from things that you want in your life. So if I want a home or a ferrari i cut out pics of expensive cars and big homes. If i want to be happy and be rich i cut out pictures of people smiling and dollar pics etc.. you catch the flow. You glue these pics onto your dreamboard and you place it right infront of your bed so it is the very first thing ur eyes see when u wake up. You close your eyes and you pretend to feel like already having those things. You really gota believe it. You do this every day for as long as you want to and before u know it, it sure comes true.

For me i tried it twice and both times worked. Why i dont use it more often? Idk. But i do however, know it works. So my question is how can something so simple in practice really make anyones dreams come true with little to no money all u need is ur brain. Can anyone explain the scientific connection between thoughhts and space
