Thanks for providing the source. I wasn't going to link it unless someone asked, and now I've been beaten to the punch!
I found it after someone was asking me more about the meaning behinds his trips and what he sees... After trying to inform him that nobody really knows and it's why we all love to explore it I came upon that site and it provided a very good read, as well as that chart.
Glad people here appreciate it!
