I'm sorry if this is the wrong place for this, I havn't been here in a while, and I was neevr really active, but I dont really know where else to ask about this so here goes: A friend of mine claims she can visualise in the 4th and 5th spatial dimensions. I've read some books by Michio Kaku and the like, so I knwo some of the basic ideas, she on the toher hand hasn't. She does however have an IQ over 190, and really is brilliant; I just don't know if I should believe her. What I was wondering was, is there anythign I could ask her, or have her do to prove she can think this way? Any help would be great. I think it's really interesting, and it would be amazing if she could, but I knwo people say it's impossible. I really dont think that she is makign this up though, as she doesn't make things up, though maybe she doesnt understand the concept (then again I might not either...) Anyways, if you have anything to say on the topic, got for it, and again, sorry if this is the wrong place for this thread.
