The Impact of Dreams

On Sleep
While dreaming is normal, there can be some abnormal parts of dreaming that interfere with sleep or overall mental health. For example, if you experience vivid dreams immediately after you have fallen asleep, it could be a sign of a sleep condition called narcolepsy.
Dreams do not typically negatively impact sleep, but nightmares can. The way they influence sleep is that it can make it more difficult to fall asleep and cause difficulty in moving between sleep cycles. This can make a person drowsier during the day.

On Daily Life
Good and bad dreams can impact daily life. Frequent nightmares may impede a person’s ability to fall asleep and then cause sleepiness during the day. Dreaming can also aid in a person’s ability to process others’ positive emotions, making the individual have a higher level of social competence.
Not dreaming may mean you are not reaching REM sleep and therefore may cause higher rates of sleepiness, depression and health issues. It seems to be that those who have negative dreams also have higher rates of stress during the day and are more likely to have sleep disorders. Likewise, those who have positive dreams are less likely to have sleep disorders. Though, it’s difficult to know the cause. Regardless, trying to think positively during the day may help the types of positive or negative dreams that occur at night.
