See this site, it's fun, with reports from around the world. Personally I believe that phenomena that we cannot explain happen, and entities we cannot see or prove do exist, but I also think that 99% of so-called 'encounters' are merely a 'aankh-ka-dhoka' or something similar...hehehe..just my opinion, what else can we humans do but conjecture on issues like these ? http://www.mysteriousreality.com/myst.asp
