Hey all. Everyone's theories are really interesting!
I have actually been watching on youtube "Matilda O'Donnel Macelroy-Interview with an Alien" & have noticed some very intriguing information..here's the link..it comes in segments.

But Anyway. This alien believes that we (humans) are extraterrestrials suffering an amnesia on this planet. The reason we can travel outside our bodies (OBE's, Astral Projection) which we have all thought was our "spiritual body" is actually our true, alien form. & that even higher, advanced extraterrestrials do a similar thing, they use some "space suit" (like our human body) as a vehicle to get things done in their world. This alien referred to us as being imprisoned here on Earth. This video is super interesting. You all should check it out!
