So i had a dream last night that my friend was lucid dreaming on a couch next to me. He even said "i'm lucid dreaming aren't i". EVEN SO, i failed to even realize i was in a dream... I've had lucids before, so i don't know how such a scene failed to "awaken" me. The weird thing is, in waking life, if anyone were to have a lucid dream, or even say the words "lucid dream" (which my friend did do in the dream), i would automatically do a reality check or something of the sorts. So what i realize is that in this dream and in many others, i am not entirely there... if you will.
Anyhow, i was wondering what are some tips to making you're dreams more susceptible to such a "hint" that you're dreaming. I believe if i knew how to have more vivid dreams, then something like this would easily trigger a realization.
