Sleep Paralysis (SP)

Q1: What causes SP?
Q2: Medically does it affect my health?
Q3: Any cure to it?
Q4: How serious is SP medically to Health?

I would appreciate if you can provide me answers to the above questions. I have experienced SP before. In total, less than 10 occasions over a period of about 5 years, if I recall correctly.
Each time, I experienced alomst the same "effects". I feel "something" is sitting/pushing against me. My whole body can moves. I can't talk or shout but I'm conscious/awake,I can see and hear the surrounding; my room. There was once I can even read the time at my clock. I also do hear buzzing sounds and sometimes some whispering noise but can't figure out the "noise-language". Normally I will "get-out" from this SP by "going" back to sleep and the next moment I'm "truly" awake;physically.
And now, I am used to this SP experience.

Dear Mudh Isa Lee TK:

Sorry to hear about your sleep paralysis.  This condition may occur in the transition from the sleeping to the waking state.  Most people describe what you tell in your posting.  Some attacks are observed in patients with narcolepsy, with hypersomnia of the pickwickian syndrome, and other forms of sleep apnea.  Usually the attacks are brief, if they occur in isolation and only on rare occasions, they are of no special significance.  If frequent, they can be prevented by the use of tricyclic antidepressants or clomipramine.  It does sound like in your case that they are not causing you any harm nor will they.  

Sincerely,

CCF Neuro MD
