It's often because the scary elements get stuck in your mind and make you anxious or nervous, keeping you from relaxing enough to sleep.
Well, it's usually because scary stories can affect your emotions and create a sense of unease. Your mind keeps replaying the scary parts, making it impossible to calm down and drift off. Sometimes, it's even a fear of having nightmares related to the story that stops you from sleeping.
Talk to someone about the story. Share your feelings with a family member or a friend. Just getting it out can make you feel better. They might also be able to offer some comfort or a different perspective on the story that will make it less scary. For instance, they could point out how unrealistic parts of the story were.
One thing you can do is to turn on a small, dim light in your room. Darkness can sometimes make the fear from the scary story seem worse. With a bit of light, you might feel more secure. Also, you could try reading a really boring book. It'll make your mind tired, and before you know it, you might just fall asleep.
Maybe it's because the comics are too exciting and keep your mind active.
It could be due to stress or an irregular sleep schedule. Maybe there is a comic that explores this issue, but I'm not sure.
Maybe the bear is too excited or worried about something. That could keep it awake.
There could be many reasons. Maybe it's stress, or too much caffeine. Sometimes an uncomfortable sleeping environment can also cause it.
It can also cause nightmares. If you go to sleep with a scary story in your mind, your subconscious may turn it into a terrifying dream. For instance, a story about a haunted house might transform into a vivid nightmare where you're trapped in that spooky place, being chased by unseen entities. This can disrupt your sleep cycle and leave you feeling tired in the morning.
Maybe it's haunted by some past events or fears. That could keep it awake.
Maybe the little bear is too excited or has a lot on its mind.
It could be because not sleeping makes you stressed and irritable, and that stress might come out in the form of creating or relating to rage comics.
