i dont know how to describe this but
in the middle of the night i woke up, got back to bed
dizzy and sleepy, random thougts coming into my mind.
start like, watching a movie in my mind while awake, sorta dreaming but i just can watch this kind of ''dream'', so my friend is taking me around this house, and i say in my mind:
god i want to have a lucid dream today!

THEN OUT OF FUCKING NOWHERE,
this white flash blinds me, i fall asleep, then i start to feel like im falling for 10 secs in a epilectic background while strange sounds play,
i try to wake up and i think i messed some shit up here because i end up in a pier, coiled into a ball, paralysed, with a statue in my front, everything in slow motion.
there is strange music playing slowly and i can hear my heartbeat, felt like yumme nikki, then i tried to woke up and did it.

tl;dr:used some sort of wake-go-back-to-bed technice without knowing it, tried to wake up during the creation of the dream, bad trip happens, also sleep paralysis in my own dream
