i used to get it very often from alcohol withdrawls along with hallucinations and some of the most psychotic and horrible dreams ive ever had.
i would be stuck that way for a long time trying not to fall back asleep because it felt like my heart was going to stop. i was trying really hard to yell but was only able to manage a groan with all my strength. in my mind i thought i was able to slightly lift my arms and legs which seemed to weigh 10x their normal weight, and tryed to get the girl i was with's attention. i thought that somehow she could wake me up or make it stop if i could only get her attention.
i thought my eyes could be forced open a crack and that i could see the room around me.
she said that i would just be barely trembling and grunting for an hour or so every morning. i would finally awake with a quick jolt to every limb and a triumphant yell. many of the things i thought i saw with my eyes "cracked" weren't really there.
the dreams i would have were insane. i felt like i was on the edge of death and saw shit difficult to explain.
i was at the end of a 5-6 month bender drinking nearly every waking hour. it eventually got so bad along with actual physical illness that i cleaned my shit up, but fuck were those last few weeks rough when my brain was almost completely melted. i guess i didn't die fast enough, ran out of money and was too much of a pussy to kill myself or go to jail; sobriety being the only alternative.
