why such troubled dreams at home?

dream of cold cerreal, long train ride, homeless outdoor people, sausages, panicked phone call in the morning. mom answering right away and whispering she can't talk righ now. hospitals.. another about a house a girl a murderer. she though the was gone and it was over. i knew he wouldn't give up. leaning on the door to keep him out of the room. no police help for some reason.
