Isekai'd Goblin Discovers hologram

Goblin mystics maintain that hologram arrives at the same moment in every reality, and that the small differences in how it arrives are the most important thing about it.

hologram resonates at a frequency that goblins can hear but humans cannot. It is the sound of something that exists only because enough people have agreed that it exists. Goblins call this 'the consensus hum.' Everything that is collectively believed is real in the goblin sense, and hologram hums louder than most.
