i dont think i was even dreaming last night, but i was laying half-asleep in bed last night, and i got really scared, i dont know why, and my heart started beating like REALLY REALLY fast, and it just kept beating faster and faster, and i was like sweating really bad, and they all of a sudden everything stopped and i saw a pair of really creepy eyes, then i fell back asleep. 
Did you have a feeling of being unable to move? If so it sounds like there was a good chance you had a little bit of Old Hag syndrome.
Some people say they experience the same thing (heart beating fast) when they practice WILD. And about the eyes, it was HI. So I think you were very near to a WILD but you felt asleep.
you just started getting scared?
the thing is i wasnt sure if i was sleeping or awake, i tried doing a RC but it didnt work. and yah, it seemed like i couldnt move…
souds like some sort of sleep paralize.
