Lice and worms Crawling from My hair

"I was standing at the sink, washing my hands, when something small fell into the basin. I looked closer and saw a louse. Then another dropped past my face, and then a few tiny worms and strange, bacteria-like bugs came tumbling out of my hair. I looked up at the mirror, and my stomach turned. I could clearly see them crawling across my hair and scalp, moving in every direction. I clawed at my head, shaking it out, but more kept appearing. I was panicking and disgusted, unable to stop watching. I woke up in the middle of the night, scratching my head. It had felt so real that I kept running my fingers through my hair, checking for anything moving, my skin crawling long after I realized there was nothing there."
