For about a year now I've found out that while caught in the sleep paralysis of the Hypnagogic State I can still move. I feel the effects of the sleep paralysis and the familiar sensation when I attempt to move as well as the fear that I sense while in the Hypnagogic State yet I've been able to open my eyes, move my arms, and barely sit upright. I don't understand this, I KNOW what sleep paralysis feels like because I've entered the Hypnagogic State dozens of times but recently in the past year I've suddenly found that I can still move while in sleep paralysis. Is this supposed to happen and does it happen to anyone else?

I felt the exact same way when I moved my limbs as I do when I can't move them.. except somehow I still feel them move but very distantly and they still move :

I've considered it might be because I wasn't deep enough in the state but having been concious in the hypnagogic state many times before I can feel how deep I am in the state and each time I moved, I was.
