Interdimensional

There are interdimensional beings present.

The idea of interdimensional wormholes is pure science fiction.

The spaceship made an interdimensional jump.

“I’m not crazy,” she said. “I’m literally just living a normal life while also, you know, discovering interdimensional communication.”

By their own mysterious yardstick, extraterrestrials and interdimensionals choose the most unlikely individuals for close encounters of the third kind on up: for starters Gilliland, Whitley Strieber, Jim Moroney, Betty and Barney Hill.
