Hi there…
Had a dream last night, trying to manipulate my dream like i used to, but at one point there was this face(from waist upwards) on a skewed angle, it was slowly fading away from me and I woke up and I could still see it as it faded out…did I really wake up? Or was I still dreaming? Any Idea’s…
You should’ve done a RC! 
I can’t really tell if you were dreaming. It could have been a FA. But it’s rather hard to tell because of so little info.
It was perhaps a hypnopompic hallucination (hypnopompic=when you wake up). It’s rare yet it may happen that you continue to see some content of your dream when waking up.
