Is it normal that i know i'm dreaming?

It's very normal. This is called " Lucid Dreaming ". It's something that doesn't happen often for most people but when it does it can be a very exciting experience. You can wish for a sexual fantasy to come true, live the life of a fictional character and etc.

There are ways to increase your chances of having a Lucid Dream. For me, I like to open a sticky note on my desktop with " I am Lucid Dreaming " on the sticky. The more I look at the sticky, the more my chances will increase of me either seeing the quote and/or saying it in a dream. Once that happens it'll cause me to become self-aware and therefore realize that I'm dreaming.

It's called lucid dreaming

Not only is it normal but it's a gift. Some people go their whole lives trying to do it.

Yep normal your a lucid dreamer

I only lucid dream so i know what your saying. I was told people who do it all the time have some sort of overly active mind scape...i day dream alot during the day too.

I don't know if it's normal, but it has happened to me. A couple of times, when I didn't like what was happening in the dream, I remember thinking something like "I don't like this. Wake up!" and I would wake up.
