Keep in mind that only some multiverse hypotheses are extradimensional. Many would prohibit viewing other universes because they don't occupy the same "space" as us. For example, one hypothesis suggests that black holes are the creators of universes (where a star collapsing in our universe occurs simultaneously with a big bang within the singularity). We'd never be able to reach that universe and so could not perceive it, regardless of exotic senses.
