OH MY GOD! i actually experienced the same way !
quick REM Sleep..False awakening... Sleep paralyze... and short period Lucid dream.
hahaha... for 5 sec... i jumped into the sky !
Scumbag brain... lol
for the REM sleep i was sleeping for two hours...
i thought my attempt to learn this lucid dream for months was actually failed...
