Scientists themselves aren’t sure why some people remember dreams while others only fragment at most. There are two types of categories for people, in your case, the ones that could easily recall the dreams every single day and the ones that only able to remember them a couple of times a month. We shall call them the “high recallers” and the “low recallers” respectively. In an experiment, the two groups are played a sound clip of their own name and have their brain activity scanned. While asleep, the clips are played at a soft enough volume that the volunteers will not wake up. The results show no difference in either of the groups’ brain activity. They are played the same clip again this time while awake. Interestingly, the research shows that the “high recallers” experience a constant fall in their alpha brain wave upon hearing their own names, in comparison to the “low recallers” of course.
In theory, a decrease in the alpha wave means a higher consciousness to respond to external stimuli, in this case, the call of their names. This occurs in both groups as predicted, as both do show lower alpha wave level while awake. However, the “high recallers” brain wave decreases for a longer period, meaning a more active brain upon hearing their name. In layman’s term, people that could easily recall their dream are more sensitive to sound while awake. Although, there is no difference for both groups’ alpha wave while asleep, it increases as expected but with the higher relative increase for the “high recallers”. If you are more likely to respond to the call of your own names, then it suggests that you will remember your dreams more.
