Some more guidepost #7 experiences: I used to take daytime naps frequently, and ended up getting a lot of experience of #7. For me there was a lot of scary phenomenology in the beginning. Often I would see flashing occult symbols, hear loud noises and feel like my body was rapidly falling or being pulled off in some direction. If I let the fear take over I would wake up. But when I eventually learned to just observe the sensations, and solidly believed that they were nothing dangerous the sequence would reliably take me directly into lucid dreams.Not sure how common these experiences are. Maybe they are more common during morning/daytime naps (and some lucid dreaming techniques recommend setting an early alarm and then going back to sleep). I almost never experienced the #7 stage when going to sleep at night, instead I would just fall asleep at some earlier step.
