Vivid Dreams

Have you ever known of someone who has "vivid dreams"? These dreams are so paramount that the person actually talks in their sleep and can really get into the situation at hand. My daughter is one of these people. Back when she was a child she would sleep walk. I'm not sure if this is a portion of those times, but it's certain that she's having strong pressurized dreams, because of the stress she's been dealing with on a regular basis. I worry for her, that these dreams will cause her health to be affected. Many times since she moved in with me, she has woke me up, yelling or talking loud about various things. It's very unnerving, to hear her doing this.
