Why Is Instant Transmission Portrayed In This Manner?

[Sovran Nila]

I'm watching the Return of Cooler, and the Instant Transmission scenes are portrayed in an interesting way. "Where" is this scene taking place in between Instant Transmissions? It's almost as if the scenario occurs "outside of time and space." So, does Goku disappear/teleport outside of his "world" and into a "state of limbo" whenever he uses the technique?

Another portrayal in Broly: The Legendary Super Saiyan.
