DETECTIVES OF SUPERNATURAL

BEST PARANORMAL RESEARCH TEAM IN INDIA

Detectives of Supernatural (DOS) is an India-based paranormal investigation team founded in 2010 by Devraj Sanyal, with its headquarters in Kolkata.The team was established with the aim of investigating claims of paranormal activity and exploring unexplained phenomena through observation, research, documentation, and investigative methods. Over the years, Detectives of Supernatural has investigated reported hauntings, unusual experiences, mysterious locations, and other cases associated with the paranormal. The team combines field investigation with technology, environmental measurements, photography, audio and video documentation, historical research, and attempts to identify possible natural or psychological explanations for reported phenomena. Contemporary coverage has described DOS as a paranormal investigative group and has documented investigations involving locations in and around Kolkata. The team's philosophy is centered around β€œRise Above Fear”—encouraging people to question unexplained experiences rather than simply fear them. DOS approaches each case as an investigation, documenting what can be observed and distinguishing between established explanations, claims, and phenomena that remain unexplained.

THE INVESTIGATION TEAM

OUR MISSION

At Detectives of Supernatural, our mission is to explore the unexplained with courage, curiosity, and an investigative mindset. We investigate reported paranormal experiences, unusual phenomena, mysterious locations, and unexplained cases while searching for rational, scientific, environmental, psychological, and historical explanations wherever possible.

We believe the unknown should not simply be fearedβ€”it should be questioned, investigated, and understood.

Through field investigations, research, technology, documentation, and responsible analysis, we strive to uncover the facts behind extraordinary experiences and separate evidence from assumption.

Our mission is not simply to prove or disprove the supernatural. It is to investigate, document, question, and seek the truth behind every unexplained case.

ABOUT DETECTIVES OF SUPERNATURAL

Founded in 2010 by Debraj Sanyal and Ishita Das Sanyal in Kolkata, DOS has pioneered scientific paranormal research across India under the banner "Rise Above Fear".

THE SCIENTIFIC APPROACH

Unlike sensationalized media representations, DOS approaches every unexplained report with skepticism and scientific rigor. Over 95% of reported hauntings are found to be natural occurrences caused by carbon monoxide, electromagnetic interference from faulty wiring, structural resonance infrasound (18.9 Hz), or psychological suggestion.

The remaining 5% of unexplained anomalies are captured on multi-sensor telemetry, thermal imaging, and calibrated audio arrays for exhaustive forensic analysis.
