the more seriously working scientists in the field of sightings investigation and research never speak of « extraterrestrials » or « aliens ». the state-of-the -art results of the latest information’s processing indicates that the so-called « UFOs » and « aliens » are neither visitors from outer space nor beings from another planet but much more « impressions » made by interactions originated from outside(!) space and time. it becomes more and more evident that our 4 dimensions are embedded in some « organizing » dimension(s). imagine people living in only 2 dimensions; imagine that they do not know what « height » or « depth » is. then imagine a ball rolling over their world. they would never be able to even imagine the form of a ball-shaped object. the same is it with the « UFOs »: they could be only ONE phenomenon, but seen from different « angles ». and only with OUR abilities of perceiving. only some special drugs such as DMT or some stronger LSD derivates could break this wall for some precious minutes.

nevertheless, you should visit some interesting sites:
the majestic documents
mufon-ces
the disclosure project
exopolitics

Are you suggesting that part of me is time traveling?
