I meant pretty much anything that can be described by wave function evolving according to Schrodinger equation.

> as for interact, what do you mean by this?

Exchange of energy through any of 3 physical forces (not gravity). So not entanglement.

Single photon universe would never be observed so it would have wave function but never have specific location so according to my idea it would not affect spacetime.
