Dream of person, surrounded

Trapped in an old fashiondimmly lit bus surrounded by people I don't know who are all talking casually, but I cant understand anything that they are saying. I sit in my own thoughts trying not to be noticed. I check my jacket pockets but they are empty. The bus is cold although I'm dressed warmly. Then I look up and see a grotesque sickly looking figure. Hes covered in lumps and seeping filth and disease and I attempt to look away. But I cant. Then the man sitting beside me begins to laugh and stands and smacks the sick person. When he does the.lumps and filth splatter over the attacker. I sit and watch but the longer I do I rrlise some of the nastiness is on me. I try to wipe it ofttimes but I cant. Its on my face and for somereason my jacket is gone and the disease is kn my arms.and in my long hair. Although in the real world I have short hair. Then I begin to cry that I cant get clean. As I do I wake up.
