Thanks for the information. I'm not really sure what my previous experience would be classed as. I've always had voices in my head shortly prior to falling asleep. Sometimes these are of people I know and sometimes of strangers but more often than not they make no sense at all. I also get very clear images of faces in my head around this time and they are usually of people I don't recognise. I have difficulty making what I want happen when I realise I'm in a dream but some dreams I have had have been so real that I have actually become frightened by how real they are whilst I am in the dream, even though nothing bad has actually happened, and begged people in the dream to wake me for fear that I would never be able to wake on my own. Also, sometimes on waking up I find that some of the images or people that were in the dream I was having are projected into my room and continue to play out for a while. I have also always had a huge elament of prediction in my dreams, with many things I have dreamed about actually presenting themselves to me in one way or another the following day. That said I still want to be able to have lucid dreams that I can control and not find threatening.
