Has anyone else experienced this?
I did last night, for the first time in my life, and it was terrifying to say the least.
I had a nightmare about a guy trying to get into the house, and then when I woke it was like my mind was awake but my body was frozen completely still.
I was trying to breathe and call out the name of the person who was sleeping in bed next to me to get their help, but I couldn't do either for a good few seconds.
Bleurgh.
@bellbird I suspect you're describing a sleep-paralysis experience.
Yes I've also had sleep-paralysis that seemed to begin with a very negative thought or frightening emotion while either drifting off to sleep or waking from sleep.
My sudden intense fear, the feeling of a weight or pressure upon my chest, also, a humming sound within my head and a very unpleasant tingling sensation slowly drifting down from my head and throughout my arms and legs with an entire body paralysis. I once observed my mother during her sleep-paralysis where she wasn't even blinking her opened eyes. I'm guessing that these experiences last about 10 seconds before diminishing. Yes, I can relate!
Sometimes, I'd noticed that when I'd do nothing, the paralysis would immediately begin to recycle all over again. It have to do with a malfunctioning or glitch during the sleep state. When I'd noticed it happening to me, I could pull myself out of it during its weakest point. It was then that I'd attempt to vocalize a sound.
@shimmerz -- I would suspect that to focus one's attention on moving one's finger would have the same effect.
The 'black cat on the chest' experience --
@Sideways I can vividly recall having this experience once during sleep-paralysis! Yet for me this was an ugly black mangey cat of average size, standing on its hind-legs on my chest while pounding its fist like hands on my sternum. I think this sort of explained the weight/ pressure and pounding of my heart that I was experiencing at that time. And when I tried to knock this imagery cat from my chest I then realized that my body was entirely paralyzed. Sleep-paralysis seemed to always occur when I was on my back also
@Elsewhere, while in bed during a lucid dream state. I'm also a side-sleeper having felt safer and less vulnerable on my side.
I wasn't aware of being unable to breathe and yet, when trying to vocalize a sound I was aware of being unable to inhale. This was all very frightening!
My awareness of having sleep-paralysis first began during my early teens yet seemed to have entirely stopped by my early 20s. I wonder if the Valium I began taking during my early 20s had anything to do with its subsidence. During my early 20s, I also stopped taking amphetamine which I'd taken continuously from age 16 to age 20. Yet I wasn't on any drugs when my sleep-paralysis first began. Sleep-paralysis runs in my family -- my mother, two sisters and grandfather did have it throughout their entire adulthood.
