I wish I could induce lucid dreaming. I'd knock myself into a coma and just relive favourite books, anime or games from different characters' points of view.
Unfortunately the finer details of all my dreams slip away about a day later, and they only last that long if I wake unexpectedly (cat jumping on my chest or door buzzing). All I remember of my favourite one was that I was competing with Lelouch and Schneizel from Code Geass for the right to inherit the Britannian throne. I'm guessing in hindsight it looks cooler than it actually was, dreams jump around a lot and I never really remember anything more than a vague overview.
