I have recently been thinking that perhaps Lucid Dreaming is not that good for our us and have put it on hold until somebody can shed some light upon my concerns.
Firstly when I was awaking at 5am each to record my dreams I noticed a lack of concentration that day at school, leaving me thinking that it was because I had interrupted some vital process of the sleeping mind (I am only 15 so my brain is still developing)
Secondly we have to train ourselves to LD thus breaking natural barriers in our mind that could be there to safeguard against dream lucidity, so surely it's not natural and may have harmful effects.
Sorry if i'm talking rubbish here but if anyone understands me please share your thoughts. Also if your just starting out don't let this put you off trying to learn, as Lucid Dreaming is a very rewarding experience and PROBABLY not dangerous.
Thanks
