Why do we forget our dreams? Does mattress quality play a role?

Our dreams are always of great interest! However, despite their vividness and sometimes deep emotional effects, many of us struggle to remember these nighttime narratives upon waking (What a shame, especially if we saw something really good)! So why do we often forget our dreams shortly after waking up?

What is the nature of sleep and dreams

Sleep consists of several cycles, each of which includes different stages, including Rapid Eye Movement (REM) and non-REM sleep. Dreams are most abundant and vivid during REM sleep, characterized by rapid eye movements, increased brain activity, and muscle weakness to keep us from acting out our dreams.

The role of neurotransmitters

Neurotransmitters play a critical role in memory and learning. During REM sleep, the levels of certain neurotransmitters, such as norepinephrine and serotonin, are significantly reduced in the brain. This reduction is thought to affect our ability to structure and remember dreams. Research has indicated that levels of these neurotransmitters are critical to memory formation, and their lack during REM sleep may contribute to the transient nature of dream memories.

Memory structure theory

Memory consolidation is the process by which temporary memories are gradually transformed into a more stable, long-term form. This process occurs mainly during sleep, particularly during the non-REM stages. As dreams mainly occur during REM sleep, when memory formation processes are not at their peak, this could explain the difficulty in retaining these experiences. Some scientists believe that because dream experiences don't always directly contribute to our survival or daily life skills, the brain may not prioritize them for long-term storage. The prefrontal cortex is involved in cognitive processes such as decision making, problem solving, and memory. During REM sleep, activity in the prefrontal cortex decreases. This decrease in activity can lead to poorer memory retrieval, making it harder to recall dreams after waking. Wakefulness and the transition from sleep The act of waking itself can disrupt the fragile state of dream retrieval. The transition from REM sleep to full wakefulness involves a significant change in brain activity and neurotransmitter levels. This abrupt change can make it difficult to hold on to the transient content of dreams. The process of reclaiming dreams For those interested in remembering their dreams more vividly, researchers suggest a few techniques.

• Keeping a dream journal and recording any dream fragments immediately after waking can improve recovery over time.
• In addition, the practice of mindfulness and meditation can enhance one's ability to recall dreams, promoting a greater awareness of inner states.

Does the way we sleep play a role?

Both the way we sleep and the quality of our mattress can indeed have a significant impact on our dream experiences, including how intensely we dream and how well we remember those dreams upon waking. Many aspects of our environment and sleep habits contribute to this phenomenon, primarily through their effects on the quality of REM sleep, where most dream experiences occur.

The effect of sleeping position

Sleeping position or posture can affect not only the quality of our sleep but also our dreams. For example, some studies suggest that sleeping on the left side may increase the likelihood of nightmares, while sleeping on the right side could lead to dreams with more positive emotional content. However, the most important effect of sleeping position is probably on sleep quality and breathing patterns. Positions that facilitate better breathing and comfort can lead to deeper, less interrupted sleep cycles, potentially enhancing the vividness and retrieval of dreams.

Mattress quality = sleep quality

The quality of your mattress plays a critical role in achieving restful sleep. A mattress that provides the right balance of support and comfort can help maintain proper spinal alignment and reduce downtime due to discomfort or pain. This can lead to longer, less interrupted periods of REM sleep, which are critical for vivid and memorable dreams.

• Support and comfort : A mattress that adequately supports the body while conforming to its natural curves can reduce physical stress and the likelihood of waking during the night. This uninterrupted sleep allows for more complete sleep cycles, including deeper REM phases, when dreams are most likely to occur.
• Temperature regulation : Mattresses that facilitate good air flow and maintain a comfortable sleeping temperature can prevent awakenings due to overheating or being too cold. Since temperature discomfort can interrupt REM sleep, a mattress that keeps you at a comfortable temperature could enhance dream recovery by allowing for longer periods of uninterrupted REM sleep.
• Reducing motion transfer : Especially for those who share a bed, a mattress that minimizes motion transfer can prevent disturbances from the movements of partners during the night. Fewer interruptions may lead to more stable REM phases, potentially affecting dream intensity and retrieval.

So the conclusion is that...

While direct studies on mattress quality and dream retrieval are limited, the indirect effects of sleep quality on dreams are well documented. Improved sleep hygiene, which includes a comfortable and supportive sleep environment, has been shown to improve sleep quality. This, in turn, can affect our dream experiences by allowing for extended periods of REM sleep, during which the brain processes emotions, forms memories, and creates dreams. Thus, investing in a quality mattress and optimizing sleeping conditions could be beneficial not only for physical health and well-being, but also for enriching the landscape of our dreams.
