  Spacetime emergence from entanglement has long been presumed to be
holographic, with emergence from quantum interactions in a boundary theory.
Since that setup is difficult to extend to general spacetimes, it is imperative
to understand the key aspects of the map from entanglement to spacetime. We
consider a scenario for spacetime emergence from quantum interactions directly
in the spacetime, where the effective spacetime theory emerges from
interactions similar to how fluid dynamics arises from molecule interactions.
We show that this ansatz constitutes a working scenario for spacetime emergence
in 2D, with explicit examples for AdS and dS spacetimes. Importantly, by basing
the emergence on interactions between quantum fluctuations that are present in
the spacetime, key aspects of the dynamics observed in gauge/gravity duality
analyses can be retained, at the same time as the quantisation can be applied
to general spacetimes.
