: Why do we get nightmares ? What decides the exact events that occur in them ?
In: 17
Dreams in general have been attributed to random signals being fired around your brain whilst you sleep to keep your occipital lobe ‘occupied’ during the prolonged darkness of sleep.
Nightmares are usually described as images that your survival instincts react to causing you to wake. Anything in a dream that happens that’s scary or dangerous for example, your brain reacts to naturally just in case it’s real.
The reason we dream, have nightmares or even need to sleep remains one of the greatest mysteries of our existence.
