I've done this.  I'll wake up and be mad at my husband, Mike.  Even though all he did, was something wrong in my dream!

Has this ever happened to you? You have a NIGHTMARE about your husband or wife . . . they're cheating on you, they lost the dog, whatever. Then you wake up and expect an APOLOGY even though nothing actually happened?

A new study at the University of Maryland found that nightmares actually DO cause real problems and fights the next day.

The researchers say, quote, "People's activity changes as a function of the dream they had the night before, specifically in the realm of close relationships."

They found that when someone had a dream where they were JEALOUS, they were more likely to report an argument the next day. When someone had a dream about cheating, they felt less INTIMATE and LOVING the next day.

There are two theories on why this happens. One, your dreams are a sign of a deep-seated lack of trust and just push it to the surface a little more.

Or two, your brain is just TESTING you to make sure your relationship is stable, strong, and what you really want.
