Dream your spouse is cheating?
It is very common when a marriage has some problems that one spouse is worried the marriage will fail and they become extremely stressed about it and may suspect their spouse is cheating. When one sleeps the brain is still active and all people dream every half hour to release the stress of the day, but most of people do not remember their dreams as they are in full REM sleep. It is the first few moments when a person wakes up (it seems longer than a few moments) that they will remember a dream or a nightmare. The best thing you can do is choose a quiet evening with your spouse and calmly (without accusing them) that you had a dream that they were cheating. Your spouse will not be upset because they know it's just a dream to them, but watch for body language and facial expressions. If you feel there is a chance your spouse is cheating then ask them right out. If they deny it and you are still sure they are cheating your only two options is to have a friend with a car and the two of you follow your spouse or, hire a detective for the days your spouse is not around.
