I worked in a prison in Carson City, Nevada. Our maintenance shop was in a very old prison right next door, which closed in 2012. Nevada State Prison, established 1860. First legal gas chamber in the US, but they also used the electric chair, hangings, and lethal injections. So, lots of executions, murders, and old age deaths. I worked a couple of days alone in the death chamber and would just ask the spirits to leave me alone, which they did. I've seen lots of light streaks, mere feet away from me. Seen many orbs as well. A couple of movies have been filmed there. An Innocent Man, starring Tom Seleck. With some real inmates as part of the movie. And another recent one, The Mustang Movie, with Bruce Dern. I've a few pictures on this computer with light streaks, see if I can find them
