Hello, last night I was trying to enter SP as soon as i went to bed. I managed to the the weird feeling in my legs then my whole body, thne I felt weightless, then really really dizzy. Then random pictures kept popping up(eyes closed). This was the furthest I had got, but then my eyes started rapidly moving about and twitching really quickly and uncontrollably, soon the SP things had completely gone

Anyone know what caused this, or how not to wake up from it?
