I wonder if Pedro could get himself a NovaDreamer (turn the signals off of course!) or an EEG and find out if the incubated dream occurs immediately after you fall sleep, 90 minutes after (first REM period) or in a longer and later period? You can try to check by waking up immediately after becoming lucid and noting the time.
By the way Pedro, you will be extremely bored of lucid dreaming by the time your “flat out” competition stops! I’m hoping to get a lucid dream every few days but not too often or I’ll get bored very quickly!
