People who tend to remember their dreams also respond more strongly than others to hearing their name when they're awake, new research suggests.

Everyone dreams during sleep, but not everyone recalls the mental escapade the next day, and scientists aren't sure why some people remember more than others.

To find out, researchers used electroencephalography to record the electrical activity in the brains of 36 people while the participants listened to background tunes, and occasionally heard their own first name. The brain measurements were taken during wakefulness and sleep. Half of the participants were called high recallers, because they reported remembering their dreams almost every day, whereas the other half, low recallers, said they only remembered their dreams once or twice a month. 

When asleep, both groups showed similar changes in brain activity in response to hearing their names, which were played quietly enough not to wake them.

However, when awake, high recallers showed a more sustained decrease in a brain wave called the alpha wave when they heard their names, compared with the low recallers.

"It was quite surprising to see a difference between the groups during wakefulness," said study researcher Perrine Ruby, neuroscientist at Lyon Neuroscience Research Center in France.

The difference could reflect variations in the brains of high and low recallers that could have a role in how they dream, too, Ruby said.

Who remembers their dreams

A well-established theory suggests that a decrease in the alpha wave is a sign that brain regions are being inhibited from responding to outside stimuli. Studies show that when people hear a sudden sound or open their eyes, and more brain regions become active, the alpha wave is reduced.

In the study, as predicted, both groups showed a decrease in the alpha wave when they heard their names while awake. But high recallers showed a more prolonged decrease, which may be a sign their brains became more widely activated when they heard their names.

In other words, high recallers may engage more brain regions when processing sounds while awake, compared with low recallers, the researchers said.

While people are asleep, the alpha wave behaves in the opposite way —it increases when a sudden sound is heard. Scientists aren't certain why this happens, but one idea is that it protects the brain from being interrupted by sounds during sleep, Ruby said.

Indeed, the study participants showed an increase in the alpha wave in response to sounds during sleep, and there was no difference between the groups.

One possibility to explain the lack of difference, the researchers said, could be that perhaps high recallers had a larger increase in alpha waves, but it was so high that they woke up.

Time spent awake, during the night

The researchers saw that high recallers awoke more frequently during the night. They were awake, on average, for 30 minutes during the night, whereas low recallers were awake for 14 minutes. However, Ruby said "both figures are in the normal range, it’s not that there’s something wrong with either group."

Altogether, the results suggest the brain of high recallers may be more reactive to stimuli such as sounds, which could make them wake up more easily. It is more likely a person would remember their dreams if they are awakened immediately after one, Ruby said.

However, waking up at night can account for only a part of the differences people show in remembering dreams. "There's still much more to understand," she said.

Recently my sleeping disorder strikes me back again, and after I searched, I was with three sleeping disorders. I had these actually a long time ago, but it doesn’t happen frequently so I wasn’t panicked over it. But recently, my friend told me that I had been laughing in my sleep which I never did this before. I know that is creepy but I asked her to listen carefully the way I laugh and determine whether it is in the same way I laugh when I am conscious.

So these are the three:

1.       Somniloquy, this one is a sleeping disorder about you talk while you sleep. Mark it doesn’t only include talks, but laughs too. 50% of kids in puberty will have this, and 4% of adult. And this runs in family, so if your parents or grand-parents have this kind of situation, you might have this too. This is not totally dangerous unless you speak your secrets when you are sleeping. Maybe that you are having conversation in your dreams and you just speak it out in real life. It will be kind of annoying if you have a roommate.

2.       Hypnogely, sleeping disorder which is specifically for laugh. You might have a cute and funny conversation in your dream, or it wasn’t you…

I before never had this in my country, but recently in Taiwan it happened and yes it was my first time ever.

3.       RBD, while this one, you act it out! Action when you are sleeping. I had a dream before where I am searching for my mom, and suddenly I woke up to find my arms are in the air, same position as I search for my mom, I was so shocked but then fall asleep again because I was sleepy.

I have never be so often in talking and laughing while I was sleeping when I am in my country, I wonder what makes me talk and laugh more often in sleep when I’m in here…

So overall these are the one that I explained and it happened to me myself. There are a lot of causes for these disorders, but I think one of the main points that make you have a sleeping disorder might be because of STRESS. As you know stress is so capable in ruining your health condition. Be sure you have your stress control!

How body works when you are asleep!



9.00 pm – 11.00 pm: At this time, your body eliminates toxic chemicals from the immune system (lymph nodes).

11.00 pm – 1.00 am: This is the time your liver eliminates poisons and rejuvenates itself. It is best to be sound asleep by 9 pm or 10 pm for your body to properly execute this important function.
12.00 midnight – 4.00 am: this is the time your bone marrow produces blood.
1.00 am – 3.00 am: This is the time your gall bladder eliminates toxins and rejuvenates itself.
3.00 am – 5.00 am: This is the time your lungs eliminate toxins and rejuvenate themselves.
4.00 am – 7.00 am: This is the time your colon eliminates poisons and rejuvenates itself. This is the proper time to empty your bowel.
7.00 am – 9.00 am: This is the time that vitamins, minerals, proteins and nutrients are absorbed in your small intestines. Definitely it is healthy to eat breakfast at this time.



Do you know?

The best time is to go in bed and asleep before 8 pm, good enough before 9pm, latest before 10 pm it is still healthy. Generally in some sense from 8pm till 10pm rest our intelligence, ability to make Balanced and Healthy decisions. From 10pm till 12 mid night rest our mind, ability to think and contemplate. Ability to cope, digest and show in healthy way our emotions. From 12 mid night rest our growth material body.
