The above title may seem odd, if not a complete contradiction. Why would anyone suggest that nightmares or anxiety dreams might be helpful? If you're in the half of the population that has experienced an anxiety dream or nightmare within the last month, then this may even be what you're wishing you could get rid of, right? Some people who had nightmares or recurring dreams early on in life even manage to block their dream recall entirely in order to stop being upset by such experiences. This unfortunate view of "bad" dreams as things to avoid is precisely the reason for the above title and for this article. An avoidance or denial approach is much like putting a Band-Aid on a car's blinking oil light because the light seems annoying. Of course, fifty or a hundred miles later, it would be greatly preferable to have understood the warning. Obviously, it's even better not to have the light blinking, but if it does, then it's important to do something about it since it's there for a good reason. One certainly wouldn't be very wise to disable it. Though perhaps not obvious, the simple fact is that most nightmares and almost all recurring dreams are similarly trying to provide an extremely valuable service to the dreamer. If we block them, we are likely missing their immediate benefit; if we remember but ignore them, we may well be missing the vital message that they are trying to bring us about our life.
