The Shadow, the brush, and the breathless Awakening

"I usually don't dream at all, but recently (the past few weeks) I've had a strange dream of lying on a cot in a dim room, unable to move. While I'm lying there, a shadowy figure (a man, I think) with blurred features stands over me. He prods me all over my body, and it feels uncomfortable, which I didn't think was possible in a dream. Then the weirdest part: he starts sweeping something across my face with a kind of really large brush, like a paintbrush but bigger. The thick, tickling thing on my face makes me feel like I'm actually suffocating, and it has a sickly sweet smell that almost made me want to gag. Soon after, I wake up and need to gasp for air, like I've been holding my breath during the dream."
