Well, I was doing the necessary things needed to lucid dream about 6months ago(one example:keeping dream journal). Then I stopped. Then last night, I went to bed early around 8:30-9:00pm and had a lucid.

I'm not going into full detail on my dream(it was very very long, probably my longest dream ever) but I was being chased by a HUGE snake(don't ask) and one of my friends walked out of a house on this street, saw the snake, and started running. Then I just guess I realized I was dreaming(somehow) and was able to change the size of the snake from large to small or vice versa. I then changed the setting to an ocean and began lighting the snake on fire with my mind. Then, after I killed it I changed the setting to an almost inside-carnival with a girl I really liked there. We danced and she changed forms into someone else(I don't know who). Then we just talked with my other friend for awhile. Then a train came and it was like I knew I had to go and wake up or something. And on the way onto the train some lady asked me what I dreamed about. I stepped on the train and woke up.

The dream really didn't matter. But it all felt so real, especially in the end. But now that I've been awake almost all day, it doesn't seem so real anymore. Is this normal?

Besides all that, after you have your first lucid dream, are you just automatically lucid? What other steps do I need to take to have more lucid dreams?
