What I mean is. Is it our protecting force. Mine for example won't let me kill anyone in a dream (lucid or otherwise). We are all "tempted " in waking life into crossing that forbidden borderline. What worries me however, can the boundaries become "blurred" by getting that much closer to one's deeper inhibitions. ps. Ever thought what it would feel like to stick your hand into a toaster. We all get those strange thoughts now and again. I just do not wish to have those thoughts amplified a thousand times and not be in control.
