This morning, I woke up to my alarm clock, and the wretched thing woke me up from a very sweet dream. I thought "NO!" and started conjuring back images and the "continuation" of the dream while trying to fall asleep.

I ended up falling back asleep, and continuing the dream from where I left off.

My question is this, what did I do? What is the term for this? WBTB?

Can I also use this to become lucid?
