Hot damn, that does happen to me sometimes, I honest to god believe there is an intruder in my room about to get me... pretty fucking scary when it happens I must admit. But then I realise its just me in the room and then back to my dreams of rainbows and forests
I sometimes get what I think you're describing where I wake up from a dream and get a sudden feeling of terror, but this isn't sleep paralysis.
I had a single instance of sleep paralysis when I was a kid. I was extremely stressed out because I'd been feeling rather ill for a good few weeks.
I remember having spent an entire week and a half on the couch; standing up for more than a few minutes would cause me to get dizzy and extremely nauseous.
One afternoon during that period of illness (which was likely due entirely to a stress disorder I realized I had later), I was taking a nap in bed, exhausted from being sick and doing nothing.
I woke up from my nap hearing my name being called. It was strange, because I didn't recognize the voice, but the voice was very distinctly talking to me.
It's like how someone can call out to you when you're not even looking in their direction, but you sense and
know you're being talked to.
Besides that, this voice called my name.
So I looked across the room and down the hall. The voice called again and again, so I called back asking, "Yes? ...Yes?"
Suddenly, the voice was in my right ear. It startled me and I was frozen in fear--I was alone in the room and this person calling to me hadn't entered from the hall.
I distinctly remember the chill that went from my skull and down my spine.
The voice, now whispering my name into my ear, was so close I could feel the breath against my face.
This is where I was so scared, I probably would have shit myself had I not been so terrified that my asshole had permanently closed shop for the day.
I remember trying to leap out of bed and get away from this entity speaking to me, only to discover that I was unable to move. Totally unable.
Being paralyzed is a strange feeling when you're consciously aware that you shouldn't be paralyzed.
Most of us are fairly twitchy all day. Whether we're tapping out foot to a tune, rapping our fingers, twiddling our thumbs, etc.
This feeling of being paralyzed is, in part, so terrible because your body isn't even subconsciously able to move in the
slightest.
It's really similar to the eeriness of being in a pitch-black cave that is entirely, completely untouched by sunlight, and deafeningly silent.
Stuck in bed with a voice whispering my name into my ear, unable to escape, and scared to the point that I became temporarily mute, I felt the fingers dig in.
Four fingers grasped both ankles, and the thumb slowly squeezed around the Achilles tendons.
I felt my ankles being forced downward into the bed, held down. Try as I might, I was unable to break free of that grip.
The voice again called me, this time from the foot of the bed.
I tried to kick free, but my legs wouldn't budge, and the hold on my ankles became painfully tight.
At that point, I felt two palms press down on my chest. Again, another whisper.
The palms pressed down on my chest so forcefully that I heard the bed creak from the weight. I was being suffocated.
After a minute or so of the attack, it seized, and I quickly sat up, still frozen from fear.
I got up and went downstairs, told my mom what had happened, and, after a few hours, carried on with my day on the couch, sick and now also afraid for my life.
Anyway, sleep paralysis is bad news and it fucking sucks and I hope none of you ever have to deal with that shit ever again.
