Last Night it Happened

I have been very passively dabbling in Lucid dreaming for about two or three years now. I have experienced some instances of lucidity and dream control. Last night however, something incredible happened.
I went to bed around 6am and laid down on my back(something I have been trying lately) I dont know how long it took. But it was as though I went from being awake, right into dream. I was not attempting this, but it seemed to go on for an hour or two. I'd say it happened about six times. I cant really describe it much better than this. I was completely aware that I was dreaming. All the dreams were very different from one another. During the last two dreams, it was as though i had complete control. Im kind of freaking out about this.
I am worried though, that I will not be able to accomplish this again. It seemed like such a fluke.
Anyone else experienced anything like this, or have any suggestions where to go from here?

I have had nights like this. It sometimes seems that once I have one LD, I can just repeatedly have them again and again until I cannot sleep anymore.

I have never figured out why it happens, and have never been able to influence when it happens. It sure is an amazing thing to have a half-dozen or more lucid experiences back to back though!

Yes i have nights like this, it's like everytime i go to sleep i have a lucid dream.

If only i could have those nights every night.

I wonder what causes them.
