I've done a sort of variant I guess. It wasn't a lucid dream per se, but years ago when I was living in Boston I had got to thinking about nightmares and how it had been years since I'd had one. Since childhood really. I thought about how emotionally charged and frightening they were to have such an impact that they often forced you out of sleep. I hypothesized that the reason I hadn't had one in so long was because I generally did not have much anxiety in my daily life. I don't know if that was the reason or not, but I decided I was going to change that. I was going to give myself a nightmare. So I committed to meditating each evening on the cusp of sleep, - really focusing on what few anxieties I did have and trying to imagine worst case scenarios playing out. I dwelt on morbid thoughts. I played Bone Machine by Tom Waits in the darkness. This went on for about a week and a half before I succeeded. I had the most mind-shattering terrifying fucking nightmare of my entire fucking life and it wasn't even close. I literally woke up screaming. Full throat screaming. I won't go into the whole dream but it ended with me tripping on the stairs of my house in the darkness and landing on the top step, cheek to cheek with the warm severed head of my best friend in a plastic bag. I have to say though, I felt satisfied when I laid back down having accomplished my mission, and in such a big way.
Well done, I guess! Props to you for examining it in such a methodical way. The next question is can you manipulate you dream content in other ways? You examined your fears and had a nightmare, so can you mentally examine you favourite food, for example, or a sport during your meditations and see how or if that affects your dreams?
I think I could if I practiced. I've had lucid dreams before, but they were incidental and only happened a couple times in my life. One thing I would try besides mentally focusing would be to set a soft alarm (not continuous like an alarm clock though) to go off at different points to try and disrupt my sleep patterns. The goal wouldn't be to wake me, but to merely disrupt deep sleep with the goal of increasing the odds that my consciousness comes to bear. But honestly I really just like good old fashioned sleep and don't feel like I get enough if it anyway :) Waking up is really my biggest challenge, -always has been. I am definitely a night owl.
