My first Lucid and a quick question!

Hello everybody! :cheeky:

Last night i had my first LD :banana:, but i was wondering something.
I did the WBTB method (where i putted my alarm clock on, so i waked up at my REM sleep and went back to bed). First i had a LD and it was actually a quite scary scenario.. But i knew it was a dream so i toyed a bit with the dream characters (putted my tong out to them :cheeky:).

But then suddenly that LD vanished i was still aware of everything i felt like i was back in my bed, but didn't move i attemped to go straight back into a dream then i felt like i was falling through my bed. then suddenly i was in a other LD i wanted to be sure that i had everything under control so did many methods yet i waked up suddenly afther 30 seconds.. :(

But my question was, when i was falling through my bed slowly (felt like i went through my body aswell if that helps). Was that the transition phase to my dream scenario or was that part of a dream itself. cause it was sucha strange feeling yet felt so normal..

Sorry for the bad english, it's not my main language :(
Really hope to get more LD in the future!!!
