Maybe during the day you saw on tv or heard about a murder, or for a brief few seconds it somehow flashed through your mind in some form, and your mind was simply flushing the buffers, so-to-speak? Dreams don't need any real meaning, my 'relationship-horror' ones tend to be influenced by the fact I overheard a conversation that day in which the words "Fancy" and "Jason" came up, and when I asked what they were on about they refused to tell me, and when I asked why my name was mentioned in combination with the word "fancy" because that's usually not a good thing one of them replied "It rarely is".
Yeah, I my female friends annoy me at times
Why not just tell me to my face. If they think I fancy one of them I can either deny it, tell them it's not true, or admit it in confidence knowing full-well it'll get to the person eventually. if they fancy me, at worst I'll just be flattered. What can possibly go wrong?
