In 'the dream scary stories', it's common to have the dreamer as the central figure. However, sometimes there might be a shadowy figure that seems to be chasing or tormenting the dreamer. This figure could be a manifestation of the dreamer's fears or some external evil force. Also, there could be other characters that appear briefly but add to the overall sense of dread, like a mysterious old woman or a creepy child.
The main character is typically the person having the dream. But in some 'the dream scary stories', there are other characters that play important roles. For example, a long - lost relative who appears in a spooky way in the dream. Or perhaps a faceless stranger who lurks in the corners of the dream world. These characters serve to heighten the fear factor and make the dream seem more real and menacing.
Often, the main character is the dreamer themselves. They are the ones experiencing the horror within the dream.
