Thanks for helping answer his question Xetrov . To piggyback off of what Xetrov said, attempting to lucid dream after about 4 - 6 hours of sleep is best seeing as REM is minimal in the first few hours of our sleep cycle. REM tends to cycle every 90 minutes (with the latter stages of our sleep cycle housing the longest periods of REM with shorter intervals).

Also, I strongly recommend getting OUT of your bed during the WBTB and keeping the lights OFF (do not let any light enter your eyes while upf or that WBTB time). You don't want your eyes adjusting to the light, that will only make it harder for them to remain still once you are attempting your WBTB. I cover many other problems/hurdles to watch out for and beat post-WBTB (for WILD's) HERE.

When you are ready to attempt to re-enter the dream state on a conscious level, I suggest doing so in a DIFFERENT location other than your bed. This reason I say this is because your mind has been heavily trained and conditioned to fall asleep as fast as possible in your bed. You will need to condition it to understand that "THIS is my bed where I go to sleep to get a good nights rest...and THIS area is my lucid dreaming area where I am consciously attempting to enter the dream state". Hope this helps.
