Well.. It seems for me, that the first time I was lucid, I just new I could control it!
This is probably because I came here, and looked up online Lucid Dreaming, and I just read things that said. You can control your dreams. So it just stuck with me. Alot of natruals say they dont relize they can control them, so. its kinda weird because they had no one tell them they can control them.
And I bet next time you LD you will be able to control them.
