I keep having this same dream every night. I dream that I am napping and someone is in my room watching me. I keep smelling a strange chemical like someone is holding a rag drenched in it over my nose and mouth. I even seem aroused in my dream like someone is fondling my genitals. Its all so strange cause it seems so real. When I wake up in the morning I still have an erection for some reason. Dreams seem so real sometimes. Its not like someone is really sneaking in my room at night, wouldn't that be crazy.
