A dream I had that involved teleprathy

I remember this one time I had a really strange and vivid dream whereby I was standing amongst strange and unexplicable urban ruins, like a warzone. For some reason in front of me was an extraterrestrial being that looked like a typical grey, although it was brownish-yellow and had various small reptilian-like scale patterns on its skin, noticable on the side of the creatures face. The thing and I had a telepathic coversation that I can remeber little of. I knew it was telepathic because no-one said anything or moved any lips. To this day I believe that this event took place in the astral plane, and that it did happen, just not in our frequency...
