Most of us dream while we sleep. For some, it’s reason to speculate on the possibility of spiritual communication, a type of assisted second sight. Others interpret dreams like tea leaves, hoping to divine the future. Some consider dreaming a process where our brains exercise, while others suppose it’s a cleaning of memories.
For not a few people, dreams can become haunting, troubling, and even terrifying. We’ve all probably witnessed friends, spouses and children twitch and turn, kick and jerk, and occasionally scream out in their sleep. We wonder what they could be seeing, and who – or what – might be visiting them in the night. Perhaps we’ve woken in panic ourselves, screaming as we open our eyes.
Dreams remain a mystery, nightmares the most mysterious. But some think nightmares are no mystery at all.
In research published in 2010 in the Journal of Neurology, nightmares were, in many cases, found to be warning signs. In many ways they are premonitions. The researchers asserted that violent dreams were often a precursor to dementia.
Diseases such as Alzheimer’s and Parkinson’s don’t necessarily sneak up on a person, but can begin decades before the most obvious symptoms appear. The scientists are convinced that violent nightmares are sometimes the beginnings of brain disorders.
This may itself be an exercise in speculation, but many doctors and researchers have associated dreams with medical conditions.
If this research holds true, some of us are carrying a little future insanity around inside.
