Wavefunction is just a math thing. Like, a wave, but in space. And time. It's like a wave, but, like, more complicated.
Entanglement is when two things are connected, like two peas in a pod, but, like, in a way that's hard to explain.
And then, like, Quantum Telepathy is just a bunch of wavefunction nonsense. But, like, with more explosions.
