Dreams have always been a source of fascination to people since the dawn of time.

What controls dreams?


What are the factors that affect dreaming?

Dreaming is an experience that can be both perplexing and bizarre. Dreams can range from the mundane to the surreal. While the exact purpose of dreaming is still unknown, there are many theories that suggest it is related to processing information and emotions, problem solving, and even creativity. But what controls dreaming?

There are several factors that can influence dreams. These include genetics, sleep cycles, environment, and even one’s own thoughts and emotions. Knowing the factors that affect dreaming can help us better understand what our dreams mean and why we dream.

Genetic Factors

Research suggests that genetics can play a role in influencing dreams. Studies have shown that people who report having more lucid dreams, for example, tend to have certain genetic variations. This could be related to the neurotransmitter acetylcholine, which is involved in dreaming and is known to be affected by genetic variations.

Another study found that people with certain genetic mutations tend to have more frequent nightmares, suggesting that there may be a genetic predisposition to certain types of dreams. Further research is needed to understand the role of genetics in dreaming.

Sleep Cycles

The stage of sleep in which we are can also affect our dreams. The REM stage of sleep is when most of our dreaming occurs. During this stage, our brains are more active and our bodies are paralyzed. This allows us to experience vivid dreams without our physical body taking part in them.

Dreaming also decreases as we age. This is likely because as we age, we spend less time in the REM stage of sleep. Studies have also shown that people who are deprived of sleep tend to have more vivid dreams and more nightmares.


The environment in which we sleep can also affect our dreams. Noise and light can disrupt our sleep, resulting in less REM sleep and less dreaming. A cluttered sleeping space can also make it harder to fall asleep and stay asleep, potentially resulting in fewer and less vivid dreams.

Thoughts and Emotions

Our own thoughts and emotions can also affect our dreams. Stress and anxiety can lead to more frequent and intense nightmares. People who are prone to anxiety or depression may also experience more vivid dreams.

Research has also shown that people with PTSD are more likely to have recurrent nightmares, suggesting that our thoughts and emotions can have a profound effect on our dreams.


Dreams can be affected by many factors, including genetics, sleep cycles, environment, and our own thoughts and emotions. Understanding these factors can help us better understand our dreams and what they mean.
