It looks as though you've gotten quite a bit of feedback that I'd think to put in. Lucid dreaming can be a scary thought, I don't think most people have these fears but they are understandable. Just the other night, and a few times before that; I had a lucid dream that ended very nervously. I walked outside of my house in the dream and heard a girl talking. She was saying "Once you've been in this state for too long, you won't be able to rise back out."

After that, I began seeing bodies of people materializing and dissapearing in front of my eyes, as if they were other people stuck in the dream state. I've known how to wake myself out of dreams since I was young, so I woke myself up. The problem was, this time I woke up into a false awakening in my bed. I woke myself up again, and again I was in a false awakening in my bed. I literally panicked for a moment thinking that I was literally stuck in the dream state. I gave one last burst that woke me into the real world, and was releaved as hell... The point of this isn't to be a scary story, but it taught me of how dreams can implement these fears into your head that make the fears- make sense even to the rational dreamer. I, and many others that have been studying dreams for a decent minute will inform you with assurity- this is not a curse. Lucid dreaming isn't a danger. There is no way to die, become ill, or become stuck in your dream state. That's not how the mind functions. With the right help, you can learn to overcome those issues. The only 'danger' of lucid dreaming, is conceptual fear and doubt. Rest easy Lonertyme.
