This is really nice post!
Sometimes I also imagine World in which every person is able to manifest they thoughts. And than I realise there is lot of evil, bad people... :( It would be interesting to see who is better in thoughts manifest: good or bad people? For me as a scientist it is one completely new field. How to get evidence (even we see them everyday) it is really just our thoughts? There are lots of studies that are on the good way... Specially in the pain treating.

Here are some really interesting articles:
