from my knowledge and from what i have read on here, SP is not harmful, just scary for some. and well, some can feel tired in the morning. i don't notice this fatigue and i can stay in SP about 30 minutes on average (the nights i do it). in some way i believe it can be as therapeutic as REM sleep for me and i welcome it. fun to explore the HIs and cool feelings. don't placebo your way into bad SP (don't believe it is scary for you)... believe it will be good, and it will be! =)

i don't have much to add about pulling yourself into the dream as i find it is quite uncontrollable for me. if i try something, it never works. if i don't try anything, i get success. perhaps just the standard passive control?
