Hi everyone

I just found out about lucid dreaming today by a post on tumblr. It seems wonderful and I'm really excited to try but I'm a bit frightened. I'm very afraid of having a nightmare and not having control (I don't usually have nightmares). I'm also afraid of not being able to wake up.
I've researched a bit and found out that sometimes you can lose sense of what is reality and what is fiction.

I really want to try this, but as you can see I'm a little scared.
