I have heard of that. I watch those ER stories on TLC and a few years ago, a girl had come in because a roach had crawled in her ear while she was sleeping. It got really deep, too. The story was kind of humorous because the doctor that had to remove it was terrified of roaches. Well, he got it out but somehow it got on him. He stripped off his ER clothes and was running around because it got on him. I would have done the same thing. I can't stand bugs and roaches are the worst! And to think of that happening in your sleep creeps me out to no end. Makes me not want to sleep.
