i went to bed at like 2am the other day and tried to go through sleep paralysis into a lucid dream straight away

i got to sleep paralysis and felt numb in my body, i remained like that for ages
and was just wondering how long it would take to finally get into a dream. i was waiting and waiting that i finally have given up

thats the other thing
to give up n go toilet then get back to sleep normally i just kinda shook the numbness and opened my eyes and got up
it felt really weird though. it cannot be explained. it was sickening and maybe felt like pins n needles. i felt my heart beating fast and was dizzy when i got up. why aand is this a serious problem or dangerous?

finally last question n nothing to do with sleep paralysis. when u see those images while ur eyes are shut
if u focus on them they kinda fly in towards ya or fly out and become smaller like theyre flying away from u. what are they and could they be used to get into lucid dream?
