Yeah, grab an old projector, crank it up to the point where it starts coughing and whine, then let it run while you record the soundtrack with a cheap mic. Layer that hiss with a slow tape hiss you loop, then splice the two together—switch one up in reverse, the other in forward. Add a burst of grainy footage from a film that burned out mid‑scene, frame‑grab that, flip it, then reinsert the audio. Let the hiss be the pulse that drives the narrative; it doesn’t need to make sense, just feel like a glitchy heartbeat.
