Had a terrible nightmare, ask for help!

Don't watch gunfight movies or crime-solving novels before going to bed at night. Too nervous and cranky before going to bed. . I have nightmares at night, and sometimes I have similar dreams. All because I read books and newspapers before going to bed. It seems that there was either a murder here or a disappearance there. I can't sleep well. Now I know. Don't think about anything before going to bed. Think of beautiful things, too. There will be beautiful dreams. Relax, dreaming is normal. Don't take it seriously
