What is a dreamwalker?

As an AI language model, I don't have any scientific evidence to prove the existence of dreamwalkers, but I can tell you what is generally believed about them in folklore and popular culture:

Dreamwalking is the ability to enter another person's dreams and interact with them. According to some traditions, dreamwalkers can control what happens in the dream, or even manipulate reality itself. They are said to possess a variety of psychic abilities, including telepathy, clairvoyance, and astral projection.

In some cultures, dreamwalking is viewed as a spiritual practice or healing technique, where the dreamwalker can help the dreamer confront and overcome their fears, traumas, and subconscious thoughts. However, in other traditions, dreamwalking is considered a dangerous and invasive act that can lead to possession, madness, or death.

In popular culture, dreamwalkers are often portrayed as supernatural beings with mystic powers, like witches, shamans, or ghosts. They appear in movies, TV shows, comics, and video games, often as protagonists or antagonists of the story. Some famous examples of dreamwalkers include Freddy Krueger from "A Nightmare on Elm Street", Rick O'Connell from "The Mummy Returns", and Doctor Strange from Marvel Comics.
