As stated , a certain part of our brain sleeps or slows down while we are unconscious . The logical judgement part of the brain – the prefrontal cortex – is off during sleep which allows our dreams to be more bizarre and illogical . Regardless , the emotional parts of the brain – amygdala and hippocampus – become even more active than in any awaken moment . Therefore , the reasoning part of the brain ’ s control over the mind decreases and the emotional parts increase ; explaining why dreams tend to leave a feeling rather than logical events in the mind .
It is extremely common for people not to remember their dreams , even though a fifth of the sleep time is spent dreaming . This case is explained by the rapidly decreasing levels of norepinephrine when we are asleep . Norepinephrine3 is a naturally occurring chemical , a neurotransmitter – sending signals between nerves – that acts as a stress hormone causing the body to feel alert and react , allowing the brain to create memories . Hence , the low rates of norepinephrine restrain the mind from turning dreams into memories . Neuroscientist , Robert Stickgold4 , states he recommends acquaintances to drink more water before sleeping to remember their dreams better .
