Hello!
Last night I dreamed that I was near a large grey door. My youngest son was with me and as we walked past it, we both heard loud aggressive knocking from behind it. I felt instant apprehension and as I felt this my son looked up at me raising an eyebrow to say something like "what's this?". Then instantly I knew it was a dream and a voice inside my head said "open it... you need to see what it is". It was at this point that I woke from the dream. is that 'knowing' part of lucid dreaming?
Many thanks!
