I have a question, this happened to me: I was trying to get to sleep paralysis to then enter a lucid dream state using the sp tutorial, but I got tired of waiting so i just fell asleep; suddenly I woke up and heard those rushing noises characteristic of deep sleep, and i thought I was going through a hypnopompic state, cause i've had those several times, and although I heard the noises and I could literally see images with my eyes closed I then must have fallen asleep because i couldn't remember anything after that, so my question is is it possible to enter a hypnagogia state after falling asleep and then waking up in that state and so forth?
