Okay im pretty new to all of this so bare with me here... Okay so i have researched this and im mainly finding out that when a person does experience this they can not move their whole body and they're stuck there feeling something heavy on their chest, but what happened to me is i saw this greyish figure walk in front of my bed i couldn't tell if it was male or female. I didn't know what was going on so naturally i freaked out. At first i couldn't move but once i started panicking i could move my upper body but not my legs i was trying to get up and fight whatever was there. I could hear it laughing and making fun of me about how i was trying to yell and fight. Then all of a sudden i tried calming down but i woke up sweating and breathing really heavy. I just wanna know why i could move my upper part of my body and not my legs. Im not too concerned about the greyish figure cause i will try and deal with that as soon as i figure out how to use my legs.

Just another question why is it that every experience i have read about has one "being" that everyone sees? Is it there to see if we are ready to lucid dream by making us fight and overcome our fears first before we can do anything?
