If you've been using continuously for a few days or more my guess would be REM sleep rebound. Even if you do sleep whilst you are using (its not impossible, i used to do it all the time) for some reason speed prevents you going into REM stage sleep. When you come down your body wants to make up for all that lost REM sleep..so instead of progressing through the stages of sleep 1-2-3-4-REM-etc. your body goes straight into REM sleep mode.
This means a lot of dreaming and in MakersTable's case, sleep paralysis, where your body goes into REM sleep mode without you being fully asleep...During REM stage sleep your body paralyses itself to stop you acting out your dreams..you dont notice it normally because you usually only go into REM from deep stage 3 or 4 sleep. When you've got REM sleep rebound, you go straight into REM sleep, when your brain is still semi-conscious and aware that it is becoming paralysed...anybody who has experienced sleep paralysis will know the frightening suffocating feeling im talking about.
