the way subliminals work at night?

[Shannon]

I have a debate-bull argument which is at night during ur sleep your mind creates scenarios of things u are scared of to bypass it and overcome it and that is the reason why we get those lucid dreams? becuse it happend to me a couple of times now so maybe thats the way it goes or a part of the process?

The reasons we dream, and lucid dream, are very complex. Processing fears is one potential aspect, but lucid dreams are another thing altogether. There are several different possible reasons I can think of why we dream, including processing events experienced during the day prior to storage, play, and others. Nobody is going to be able to definitively tell you an answer, though, because nobody can definitively prove their ideas. Lucid dreams are even more complex.
