. The existence of ghosts (scientific haunting?)
"Information residue" theory: ** Ghosts are not souls in the traditional sense, but "information residues" left in the real world after strong emotions (fear, obsession, resentment, unfulfilled wishes) resonate with specific time and space environments (geomagnetic field anomalies, special minerals, water veins). Similar to holographic projections or data packets.
* **Existence form:**
Image type: the most common. It can only reproduce specific scenes or actions (such as the woman in white on the stairs, the shadow repeatedly jumping off the building), has no entity, no intelligence, and has no impact on the environment. Trigger conditions: specific time, light, magnetic field strength, and the presence of a "receiver" (a person with a sensitive constitution or a specific device).
* **Interactive:** Stronger residual body. It can have a weak physical impact on reality (such as moving small objects, creating cold wind, and making sounds), and can even conduct simple logical conversations (but with a fixed thinking mode, like AI). Triggering conditions: strong obsession (place of death, beloved objects), specific media (old things, photos), contact with people related to the obsession.
Possession Type: Extremely rare and dangerous. Strong information residue invades the consciousness of living people and attempts to "cover" or "rewrite" the host's information. The host will exhibit unusual behavior, powers, or knowledge. Trigger conditions: The host's spirit is extremely fragile, highly resonates with the residual body information, and comes into contact with the core obsession.
