Sleep paralyses creatures or forces don't want 's_x' from you, what they want is to absorb your personal energy, to dominate your very being, and that's what's so scary or uneasy about these encounters.
Like the movie 'The blob'..
Like the movie 'The blob' it's more like these entities want to 'absorb' you into themselves.
And that's where that 'I must snap out of this now' urge comes from.
It's the feeling of being absorbed into something else, invaded, that's so uneasy.
Hard to explain unless experienced.
It's the feeling of having personal space violated x 10.
These beings do exist, and when they toy with you one night, you will blog about it to or express in some other fashion.
But you'll realize these are forces outside of your own will.
Quick non linked notes about sleep paralisis dream.
1. Silvery fish scale like hands pressing down on chest as slept, but in mocking manner, no comfort at all, cpr position on chest, but restoring life was not intent of silvery fish scale colored hands.
2. While laying down, entities knocking feet around, slapping feet around, in ugly way, mocking way, as if to say 'We hate you, can't stand you, and only want to mock you'. These entities slapping feet around had nothing but disdain in them towards myself and or maybe other humans.
