This is such a weird phenomenon that I've experienced more than once in lucid and non-lucid dreams, but I've actually had false memories. Recently, I had a non-lucid dream that I visited a camp that I never went to and started reminiscing in false camp memories with a counselor I "remembered." I discussed the field trip I never went on and talked about all the photos I never took. It all felt so real they they were real memories! Crazy. Anyone ever experience anything like this?
