You’re paralyzed. Or you’re flying over your childhood home. Maybe you’re just standing in a grocery store trying to buy milk, but the milk is actually a stack of old newspapers. It’s weird. It’s vivid. Sometimes it’s terrifying. Most of us spend about two hours every single night lost in these internal movies, yet we usually wake up and forget 95% of the plot before the coffee pot even finishes brewing.
When I dream at night, my brain isn't just "shutting off" for the day; it is performing a high-stakes data migration.
Think about it. Your brain is a biological supercomputer that never actually takes a break. While your muscles are relaxing and your heart rate slows down, your neurons are firing like crazy in the visual cortex. It’s a paradox. You’re fast asleep, yet your brain is almost as active as it is when you’re navigating a busy intersection or arguing with your boss. This isn't just random noise. It is a fundamental biological necessity that keeps us sane.
The REM Stage: Where the Magic Happens
We used to think sleep was a linear path from light to deep. It’s not. It’s a cycle, and the heavy lifting for dreaming happens mostly during REM (Rapid Eye Movement) sleep. This stage usually kicks in about 90 minutes after you drift off. Your eyes dart around under your lids. Your breath gets shallow. Your limbs go into a temporary state of "atonia"—basically a safe form of paralysis so you don't actually punch your nightstand while dreaming about a boxing match.
Dr. Matthew Walker, a neuroscientist and author of Why We Sleep, describes REM sleep as a form of "overnight therapy." It’s the only time your brain is completely devoid of the anxiety-triggering molecule noradrenaline. This allows you to process emotional memories in a "safe" chemical environment. When I dream at night, I am essentially stripping the painful sting away from the day's events, leaving behind only the useful information.
If you skip out on this stage—maybe because of a few glasses of wine or a late-night Netflix binge—you aren't just tired the next day. You’re emotionally reactive. You lose the ability to read social cues. Ever notice how a minor inconvenience feels like a tragedy after a bad night's sleep? That’s your missing REM cycle talking.
Why Is Everything So Weird?
Why can't our dreams just be logical? Why can't I dream about filing my taxes correctly instead of dreaming about a giant lizard chasing me through a library?

The answer lies in the prefrontal cortex. That’s the part of the brain responsible for logic, planning, and impulse control. During REM sleep, this section goes dark. It’s basically offline. Meanwhile, the amygdala (the emotional center) and the hippocampus (the memory center) are running the show.
Without the "Logic Police" on duty, your brain starts making associations that it would never make during the day. It connects a memory from three years ago to a fear you had this morning. This isn't a glitch; it's a feature. By making these wild, non-linear connections, your brain fosters creativity and problem-solving.
- Dmitri Mendeleev reportedly saw the structure of the periodic table in a dream.
- Paul McCartney woke up with the melody for "Yesterday" fully formed in his head.
- Mary Shelley came up with the idea for Frankenstein after a vivid waking dream.
When I dream at night, I am essentially allowing my brain to brainstorm without any ego or logic holding it back. It’s the ultimate "out of the box" thinking session.
The Nightmare Factor
Not all dreams are pleasant. Some are downright brutal. Nightmares are often your brain’s way of "threat simulation." This theory, championed by researchers like Antti Revonsuo, suggests that dreaming evolved as a survival mechanism. By simulating dangerous situations—being chased, falling, losing a tooth—our ancestors could practice their reactions in a risk-free environment.
If you’re dreaming about being unprepared for a presentation, your brain is likely rehearsing for a high-stress event. It’s a dry run. It feels real because, to your amygdala, it is real.
However, there is a difference between a standard nightmare and a "night terror" or chronic nightmare disorder. If the same traumatic event repeats perfectly every night, the brain isn't processing the emotion—it’s stuck in a loop. In these cases, the "overnight therapy" has broken down.
Lucid Dreaming: Taking the Wheel
Most of the time, we are passive observers in our dreams. But for some, the realization hits: "Wait, I’m dreaming." This is lucid dreaming.
It’s not just New Age fluff. It’s a verifiable neurological state. Studies using fMRI machines have shown that during lucid dreams, parts of the prefrontal cortex actually "wake up" while the rest of the brain remains in REM sleep. You get the best of both worlds: the unbridled creativity of the dream state and the conscious control of your waking mind.
Can you learn it? Yeah, usually. It takes practice—checking your watch twice or trying to push your finger through your palm during the day. Eventually, you’ll do it in your sleep. If your palm feels like smoke, you’re in. You can fly, talk to your subconscious, or just explore a world your brain built for you.
The Physical Toll of Dreaming
Dreaming isn't just "in your head." It has physical consequences. During REM, your body’s internal thermostat shuts off. You stop shivering or sweating effectively. This is why a room that is too hot or too cold can kick you out of REM and leave you feeling like a wreck the next morning.
Also, your heart rate and blood pressure fluctuate wildly. For people with certain heart conditions, the intensity of when I dream at night can actually be a period of physical risk. It’s an incredibly active state for something called "rest."
We also have to talk about "Dream Incorporation." If a car honks outside your window, your brain might turn it into a trumpet in your dream. Your brain is trying to keep you asleep by weaving external stimuli into the narrative. It’s a protective mechanism. It wants you to stay in that restorative state as long as possible.
Myths We Need to Kill
We’ve all heard that if you die in a dream, you die in real life. That’s nonsense. If that were true, nobody would be left to tell the story.
Another common myth: you only dream in black and white. While some people do, most people dream in full color. Studies suggest that people who grew up watching black-and-white television are more likely to have grayscale dreams, which tells us how much our media consumption shapes our internal architecture.
Finally, the idea that "dreams only last a few seconds" is a total myth. Dreams occur in real-time. If you dream about walking down a long hallway, it takes roughly the same amount of time in the dream as it would in reality.
How to Actually Remember Your Dreams
Most people say, "I don't dream."
You do. You just don't remember them. If you wake up and immediately jump out of bed to check your phone, you are wiping the "cache" of your dream memory. The transition from sleep to waking is fragile.
To hold onto the images of when I dream at night, you need to stay still. Don't open your eyes immediately. Let the images linger. Keep a notebook—not a phone, because the light will kill the memory—on your nightstand. Write down anything. "Blue car." "Cold wind." "I was angry." The more you record, the more your brain realizes this information is "important," and it will start to prioritize dream recall.
Actionable Steps for Better Dreaming
If you want to optimize this "overnight therapy" and improve your mental health, you have to treat your sleep like a professional athlete treats their training.
- Kill the Alcohol: Wine might help you fall asleep faster, but it is a notorious REM-suppressant. It literally blocks the dreaming stage. You might be "unconscious," but you aren't dreaming, which is why you feel so emotionally fragile after a night of drinking.
- The 65-Degree Rule: Keep your bedroom cool. Since your body can't regulate temperature well during REM, a hot room will wake you up and cut your dreaming short.
- Consistency Over Duration: Going to bed at the same time every night helps your brain predict when it can safely enter the deep REM cycles.
- Morning "Dream Lag": Give yourself five minutes of silence when you wake up. No TikTok. No emails. Just sit with the remnants of your subconscious.
Dreaming is the most sophisticated virtual reality system on the planet. It’s free. It’s built-in. And it’s the only time your brain is truly free to play with the raw data of your life. Pay attention to it. Your "dreaming self" is often much smarter than your "waking self."
By prioritizing your REM sleep, you aren't just getting rest; you’re giving your brain the space it needs to heal, create, and solve the problems that seem impossible during the day. Respect the process. Turn off the screen. Let your mind take over the narrative.
To improve your dream recall immediately, place a physical notebook and pen next to your bed tonight and commit to writing down the first three words that come to mind the moment you wake up tomorrow. This simple act signals to your subconscious that you are ready to listen. Repeat this for seven days to notice a significant increase in the clarity and length of your remembered dreams.
For those struggling with recurring nightmares, look into Imagery Rehearsal Therapy (IRT). This involves writing down your nightmare during the day but changing the ending to something positive or neutral. Mentally rehearse this new version for five to ten minutes daily to "reprogram" the dream sequence. If sleep disturbances persist or affect your daily life, consult a board-certified sleep specialist to rule out underlying conditions like sleep apnea or REM sleep behavior disorder.
