So last night i had a lucid dream after 5 nights of trying. It started out as a normal dream. i was walking and pinched myself to see if i was dreaming. I did it a few more times and i realized i was dreaming. I tried to show my friend but nothing i tried worked. It was just a normal dream and when i became lucid, it just continued on. It was vague and not really exciting. Why wouldn't anything work? Also it only lasted a minute, how can i make it last longer and become more vivid?
