First, hello to everyone of the community. I am a newbie and I want to learn how to LD.

I've read about lucid dreaming for the first time now on the site and I felt curious about it.
But I have a question first. LD is more tiring than a normal sleep or is it the same? I remember I had once a lucid dream and I woke up mentally exhausted. Is that normal or it was how I "lived" my dream that actually tired me out?

Thanks in advance.

PS: Please excuse me for my English... I know it is awful
