So in string theory, the extra dimensions are considered compactified at scales smaller than we can observe. My question is essentially are we supposed to be contained in a higher dimension, or are the 'higher' dimensions contained in our dimension?

I've been looking at a lot of Wikipedia pages and asking chat GPT with mixed results and I'll be honest I'm not that advanced at physics. So basically, my confusion is with compactified dimensions, are all these dimensions contained within our space, or they just integrated with it? Like could you still theoretically travel/phase between these dimensions or are they just super small and irrelevant to such perceivable actions. Either way thanks for giving me the time of day, and I appreciate any answers.
