At first I wanted to post it in the "the secret has sold over 500k copies" thread but in this one it would be a lil bit more on topic. Only a little because it's not that recent...it happened 7 years ago(1999).
Yes, I manifested a bike.
I had wanted a fancy blue mountain bike for a while, I could stare at pictures of a bike almost endlessly and frequently rode my old bike and imagined I was riding my new shiny and... faster

At summer I was at my grandparents for some weeks and one day my mother phoned and told me there's a bike waiting for me... It was actually the very same bike I wanted most amongst all other choices too. I stayed at my grandparents for a while and actually wondered whether I'm maybe actually dreaming and it's a delusion but it wasn't...
