San Diego is the nation’s most haunted city, according to ghost hunter and native San Diegan Michael Brown. We went on his ghost tour in Old Town, a historic street lined with old-fashioned saloons and shops.

Michael, who speaks in a monotone, has spent the past six years scouring Old Town at night and documenting his supernatural encounters. In this photo he’s playing us an “Electronic Voice Phenomenon” or “EVP” of what (to the untrained ear) might sound like dogs barking, but is in fact a ghost couple fighting.

If you look carefully at this snapshot taken in Old Town’s El Campo Cemetery, you will notice a circular thing floating in the background. Facilitator Jackie Goodrich believes this is a reflection from the camera’s flash, but her co-facilitator Piya Kochhar (who incidentally took this shot) maintains this is an “orb” or “entity” from the other side.
