Making progress! But need some answers please!

Ok so i finally made some progress last night, i got to the heavy sound/vibration phase. but unfortunately, i think i fell asleep immediately after that, because i can't remember a single thing after seeing a lot of twists and turns from my eyes....anyways, weird thing is I got to this stage without really "focusing". but i was actually telling myself "i will wake up after vibrations, i will wake up" i got to this stage instead, by thinking of regular things in my life, like the Olympics...wait, while im typing this, i just remembered one thing...i did wake up in the middle of the night, aware of what was happening and i tried to get up (from sleep paralysis) but i actually did get up physically rather than astrally :/ is all of this normal? is it normal to fall asleep? is it normal to not remember after vibrations? is it normal to force urself out of paralysis physically? when im in paralysis how can i force myself out spiritually instead? thank you!
