Are you one of those people who have frequent nightmares? Do you get scared during sleep about some things related to the future including ghosts? So all this is nothing but the elasticity of your brain. Actually, the problems in your brain and your emotional health are such that due to this you start having nightmares. To understand this, you have to understand the science of your brain that goes into the world when we start having scary dreams. So, let us know what is this elasticity of the brain that takes us into the world of horror.

The biggest role behind having bad dreams is the health of your brain. Actually, this happens during rapid eye movement (REM). Actually, this is a phase of sleep, which occurs due to irregularities in heart beats, rapid breathing and rapid eye movements. According to Harvard researchers, nightmares occur when the REM period becomes longer and due to this, sleep becomes unstable and the brain simply creates distorted things and sees nightmares.

Post Traumatic Stress Disorder (PTSD) is when a person has gone through some trauma. This happens in those people who have gone through some great shock and sorrow. This problem is more common in people who have suffered physical abuse or an accident.

People face this problem more due to stress, irregular sleep, consumption of medicines and some mental disorders. Also, people suffering from mental illnesses like bipolar disorder, depression or schizophrenia are more likely to have nightmares.
