How do you define ambience? It goes beyond just sound, which is what sleep ASMR is generally categorized to be. Ambience is the sensation of depth as well, where you might be able to hear something further away, and something closer as well. You might almost be able to smell the crackling fireplace as it consumes the redwood in the corner. The heat radiates across the room and you feel it seeping into your aching bones. You start salivating as you smell food cooking in a kitchen.

OK, OK, not sure if a video can do all that, but that’s what I’m getting at. Videos with good ambience can do all these things because they immerse you in a different world. Not sure if these ones below will do the trick, but they might start getting you there.
