yeah re-entering works great!! i highly reccoment it. often times when I'm having an LD it will fade to black sooner or later leaving me concious and awake but with my eyes still closed...if you keep your eyes closed and just imagine something...i always imagine looking at my hands because I do that in LDs a lot, but I suppose it could be anything...pretty soon that imagined object will start to materialize in front of your eyes and then more dream elements will manifest around you and if it works right you can just conciously enter the dream
