Is sleep paralysis real?

Yes. I used to get sleep paralysis all the time. I couldn't move and eventually I could move if I tried hard enough just like your description. That's pretty common. Don't worry they're just dreams.

Only when you cant wake up when having a bad dream

ya it's real... it happens to me when my sleep is ****** up, sleeping too much or too little. you are not a special snowflake

Yes , when U r facing difficulties in real life which u r not able to coup with which lead to see u such weird and scary dreams may result to dream paralysis

Go to the Doctor and ask him/her to help you overcome this type of paralysis.  I would not go through Life with it, if there is a way to heal it.  Maybe you enjoy feeling "special' and that is why this paralysis continues.  Think about that for awhile, and see if there is some way to make a change. 

Yes, it's real.

Sleep paralysis is a medical condition (of unknown origin) where a normal physiological process associated with REM sleep overlaps stages of awareness where it normally doesn't exist.

It's normal for your body's neural signals to be blocked during REM so you don't unconsciously try to act out your dreams, and injure yourself in your sleep.  The dysfunction that presents as sleep paralysis is when that block persists into the period when you are waking up.

The hallucinatory impressions associated with it are the result of one part of the brain essentially still dreaming, while another part thinks it's awake.
