Helen, your dream is deeply intricate and layered with various symbolic meanings. The introduction of an evil lady trying to summon the Demon King by killing a rare species of crab suggests a confrontation with a destructive force, possibly representing an external threat or internal conflict in your life. The rare crab could symbolize something precious and unique to you that is under threat. Your attempt to stop her by going back in time, and then calling the police, indicates a strong desire to correct past mistakes or prevent negative outcomes using both unconventional and conventional methods.
When the dream shifts to the group of men in the store, with the leader who only has hair on the side of his head, it presents an image of someone who is incomplete or missing something essential. The frozen donuts with supposed magical properties reflect a search for a quick fix or an easy way out of a difficult situation. The leader's disappointment when the donuts do not grant the power to time travel underscores a theme of unfulfilled expectations and the realization that some problems cannot be easily solved.
The introduction of the portal and the transformation into a Minecraft character signifies a transition into a different reality or state of being, perhaps an escape from the mundane into a more imaginative or simplified existence. Meeting Link from 'The Legend of Zelda' and then morphing into him suggests a merging of identities and a quest for heroism or self-discovery. The desire to visit the amusement park, which is not yet open, indicates a longing for joy and adventure that is currently out of reach.
The scene in the mental hospital filled with monsters and demons represents a chaotic environment, possibly mirroring internal turmoil or external stressors. Seeing your friends in the lobby, and learning that one of them has a crush on you, introduces a personal element of support and affection amidst the chaos. Your determination to find and rescue your friend highlights a sense of loyalty and bravery.
Finally, discovering the secret room where you transform into a demon and your friend into an angel symbolizes a revelation of true natures and the duality within yourself and your relationships. The decision to defeat the Demon King together signifies a united front against a common adversary, but the dream ending before knowing the outcome suggests unresolved issues or ongoing challenges in your waking life. This rich tapestry of images and events in your dream reflects deep-seated emotions, desires, and conflicts, providing a fertile ground for further exploration and understanding.
