A nice mystery theme, slightly inspired by films and series such as The X-Files and many others. Think crime investigation, forensics, mysterious evidence, detective cases. CSI meets X-Files meets Forensic Investigations meets Missing Without a Trace etc.
Menacing low pulse morphs into unnerving low drone with undulating, exoteric textures. Conjures feelings of dread, tension, and disorientation. Good for psychological thrills, stand-offs with deranged abductors, or terrified confusion brought on by threat
