During the late `1960's I was experimenting using a hypnotic trance state to astral project myserlf half way across the United States to a very specific location. I believe that I did this successfuly several tines. As I left my body I soared through the sky like Superman, looking down for reference points to guide me to my destination. As i neared that destination, I felt myself slowing down as I focused in of a specific building and then felt like I was looking through transparent walls into the target apartment. It was real enough that I described the layout and contents exactly to the occupants later on. I only did this a couple of times, just enough to convince myself that astral pojection is real and that I could do it. It kind of made me feel like a "peeping tom".
