I don't think aliens come from outer space. I think they come from here, from earth, but from different dimensions. I think they've figured out a way to cross dimensions. I think when we sleep and sometimes when we have very traumatic experiences or do intense psychedelic drugs or achieve states of deep meditation, we can cross those dimensions as well. We just haven't figured out how to move anything beyond our own consciousnesses into the other dimensions ,where they seem to be able to move so called "space craft" around. They're probably smarter than us. I think sometimes when we dream what we dream about is real, only it's happening in another dimension. I think aliens used to show up looking like leprechauns, and then looking like fairies, and then they developed the typical alien disguise in recent memory. I am totally serious! Of course, I'm not doing any justice to the subject by discussing it in this manner but I wondered what other people thought about this.
