So tonite walking back from the movies I looked up and saw what can only be described as the strangest thing I've ever seen and believe me I've seen some weird things..this thing rose up out of nowhere and came drifting by right above my head silently and slowly so that i could get a good look at it..It was at first a very bright orange thing but as it passed above me it looked like a translucent upsidedown glass with a bright orange fire ball spinning around inside of it..It was huge..It kind of reminded me of a jellyfish for some reason..I tried to film it on my phone camera but it mysteriously wouldn't turn on..a guy on a bike was driving by and I yelled to him to come check it out..he came over and couldn't believe what he was seeing..he kept saying.."oh my god what the hell is that" and "i've never seen anything like it before"..it was weird and seemed to be conscious and reading my thoughts..we both watched this thing sail above us so gracefully and silently just in complete awe..it drifted for a while getting brighter and brighter and finally just hovered to the bottom left of the moon..as I write this it is still visible..so if anyone has seen this thing tonite let me know..its a mystery and I have at least one other witness..surely someone out there has seen this above Cambridge..strange things are happening above us and probably below us! too!
