WBTB (instant LD)

WBTB stands for "wake back to bed" and is a Lucid dreaming technique used to get instant results and are very vivid
and easy to control due to the alertness gathered during the the wake phase

>How does WBTB work ? (basic)
WBTB involves waking up during a REM stage in which you're dreaming
pausing the dream when you wake up and once awake doing something to keep your mind occupied but still tired
allowing to be more conscious as you fall asleep resulting in an instant Lucid Dream

>When are the REM cycles?
each cycle happens every 90 minutes (1 hour 30 minutes) with the first being 10 minutes
and the last being an hour (common cycle used for WBTB) the last cycle is around 6 hour of sleeping to get to the start of it
