A study found that those that have a nightmare about their sweetie are more likely to get into a fight with them the next day.

If you have a bad dream about your sig other, let's say they cheat or something. Do you wake up the next day expecting an apology or you have that feeling like you don't want to be around them?

You are not alone. Many are feeling this way and because our dreams can be so vivid and life like, many people wake up feeling like their significant other should apologize. When they don't, that image remains with you for the whole day. By the time you get home from work you are ready to get the boxing gloves on.
