I think it's very possible that this could be a lucid dream. A lot of my early lucids were like this, with this weird understanding of having a dream body and knowing that I also had a physical body. Usually preoccupying myself with the thoughts of my real body would lead me to focus on it and wake myself up (so if it sounds like that's why you woke up, next time try not to!)

I can't say if it was a WILD or not, and unless you tried to move and couldn't no one knows if you were in sleep paralysis (though if you woke up and couldn't move it's very possible that you were). There's no such thing as a 'mild case' of SP, you either are or aren't paralyzed. With this few details it's hard to know what you mean that you were dreaming and awake. Were you just drifting off and suddenly found yourself in a dream?
