We have been living in the same flat for almost 7 years now. When I was about 13, I'd been going to bed quite late so I didn't get enough sleep especially when it's weekdays. That was when I started to experience Sleep Paralysis. I usually get woken up unable to move and unable to make sounds. It happens once or twice a week but then last week I've been experiencing it every night! Not only that but I woke up whilst paralysed with something or someone holding my neck tight which made me unable to breath like I normally do.
My eyes are completely opened wide and nobody's even there. I tried calming myself like I would do when I'm having sleep paralysis but since I'm having a hard time to breathe, it made me go all panicky. I was then finally released from choking and after that I didn't go to bed. I just... Prayed. I told my mum and she told me I might have been sleeping in a wrong position.
Nothing happens to me at the moment when I'm sleeping. So I guess everything is quite okay now. However earlier about 4 PM, I arrived from school because I had to attend something with my friend; My dad angrily shouted at me 5 times somewhere in the flat calling me by my full name and I was a bit surprised. I rushed upstairs asking my dad what's wrong and my dad never responded. I then realised that I was all alone! I was still spooked out but I never let fear take over me.
Sleeping is the time in which your brain shuffles around data for the day, it takes memories, moves them around and decides what to keep and what to get rid of, what to store in long term memory and what goes into short term.
During your deepest stage of sleep you dream. During this time your body usually disconnects itself in an attempt to protect you from thrashing around.
Sleep Paralysis occurs when a person wakes up quickly while the brain is still disconnected from the body. You will be temporarily paralyzed and in some cases your brain will still be in dream mode.
During this time your brain can actually project things on to the real world environment. Imagine you are looking through a set of old school red and blue 3D specs. The red is reality and the blue is your mind. For a limited time the red and blue merge and you can see stuff while you are awake this can lead to sometimes horrifying events. I am told you can also *hear* things that are not there.
As for the lack of breath, gasping for air, it could either be a side effect of sleep paralysis or sleep apena where you stop breathing in your sleep. If the problem persists, see a doctor.
As for a recurring dream, it happens, it's not at all uncommon, its not uncommon to pick up a dream from where it last left off either. Trying to analyze a dream is like trying to prove the existence of God.
