In a lucid dream, it can be so magical to experience all sorts of possibilities. For me, nah.
Do you know the feeling of watching your self confessing to a random person, moreover stranger at that? Well, it sounds trivial.
But, what if it happens everytime you sleep? If you get a constant rejection, you will end up waking up shortly and barely sleep.
If not, you will experience a long deep sleep that it is so hard to force yourself to wake up.
What a useless trait! If it continues, how am I supposed to do my training?!!!
