I have had so many experiences like this that I couldn't count them all, or remember most of them (100's to 1,000's)... But I'll start the thread by sharing one of the latest experiences that happened a couple weeks ago:

I was in a local thrift shop browsing through the books section, when I had an idea that I could possibly find a substantial amount of ca$h in one of the books. So I began to imagine a healthy stack of cash/bills with a 100 dollar bill on top. 

My current vehicle was beginning to have several 'problems' and I thought this could help me to pay for another, much more reliable one, and with around 50,000 less miles on it than my current one... which I had paid only $740 for, a few years ago. I was also visualizing to find the same model vehicle as I had and in very nice physical shape/condition, with a mechanical issue that I could fix myself.

I had almost completely forgotten about my 'money in the book' idea a couple days afterwards, while out of town at a different thrift shop and starting to look at the books there. (This is one of my regular things to do at thrift shops, and I have quite an extensive obscure book collection now.) I think it was only the second book I picked up and I just quickly scanned through the pages and briefly saw something that looked like money. I went back to that page and to my amazement saw a $100 bill, with several other bills under it! I closed the book and bought it for 99 cents. The book title was "Dreams", by Carl Jung.

So a few days later I saw an ad on Craigslist for the same kind of vehicle I was looking for, and went for a 2 hour drive with a friend to look at it. I ended up buying it for $600 that day, but it didn't have reverse, so I found another good used transmission for sale on Craigslist for $150. I drove another 1 1/2 hours a day later to 'extract' the used transmission from a different vehicle. (A job I had never attempted before.) It took me almost a full day of work to remove that transmission successfully, and another 2 days to have it installed on my 'new' vehicle... and it ran perfectly fine after installation, and with no leaks. :)
My 'new' car was in excellent condition, inside and out... and had 49,000 less miles on it than my previous one. It also had a roof rack and a tow hitch... two more things I visualized and didn't have on my previous car. Additionally, it came with almost brand new tires and alloy rims... also details I had envisioned having. The money in the book covered almost half the cost of the 'new car'.

Anyone else have any other amazing stories to tell/share?... Or any questions for me?

PS... I've found this manifestation 'business' to have a very basic formula, find it to be easily repeatable, and I experiment with it often.
