This is something I've been wondering: I've recently needed to start taking sleep aides due to my circadian rhythm disorder. Since starting with these aides, I've found that not only are my dreams a lot more vivid but I also have had a much easier time remembering my dreams (or at least bits and pieces of them). However, the strangest thing that has started happening is that there are completely fictitious characters, created by my subconscious apparently, who appear in multiple dreams - sometimes days or weeks apart. I've heard of people having fictional characters or real people they've never met show-up in their dreams more than once but I've never heard of anyone who have had characters who only appear in their dreams show-up more than once. So, I was wondering if anyone on this forum has had that happened to them?
