Why do we dream?
When we shut our eyes and go to sleep, sometimes our minds dream up stories that can feel as real as when we’re awake.
Dreams can be described as emotional, sensory and cognitive occurrences during sleep. They can be fun, happy, scary, sad or just outright bizarre and are often a topic of fascination for scientists and doctors.
While we don’t remember around 95 per cent of our dreams, it is thought that all of us have three to six of them every night.
These dreams only last around 15 to 20 minutes and we usually don’t have much control over what the dream is about, what we see and feel, and what parts of the memory are used.
Why we dream, how we control the content and what they signify are questions that many people want answered.
Experts at House Call Doctor say that there many possible reasons as to why we dream:
- Dreams can represent unconscious wishes and desires
- They help process information and moments from throughout the day
- They interpret different signals from the body and brain while asleep.
Many researchers theorise that dreaming helps with developing cognitive functions, prepare you for possible future threats and represent long-term memories.
However, nightmares are upsetting dreams that can cause you to feel many troubling emotions, such as fear and anxiety.
The causes of nightmares can include:
- Emotional difficulties
Many people like to try and interpret what their dreams might mean. Often what we think about right before we go to sleep influences what we dream about.
There is still a lot we don’t know about dreams, as they’re very hard to study. However, new technology may help the way we research dreams and could change our understanding of them in the future.
