What does this dream mean?

My friend Jessica had a dream around Christmas time, and she just told me about it not, it’s about a current situation in her life with a guy who asked her for money in the past. She started talking to this guy again around October. My friends, and I told her, “What if you got pregnan,” and we warned her about another consequense that could happen as an outcome to her situation. Here’s her dream; It was pitch black, some guy kept saying, “You really want to know!? He will just keep taking, and taking, and taking, and taking, and taking, and taking and taking.” (She said she was tossing, and turning that night). Jessica comes from a religious family, so she thinks that dream was a warning. So another qestion she had for me was; why wasn’t she warned in her about the consequences my friends, and I say could happen? Does God warn people in other ways to about what could happen?
