Through practice, mostly. Start by trying to imagine a sphere in 4 dimensions: it provides an example of a curved *three* dimensional manifold.

I might recommend the book 'The Shape of Space' as an introduction:

Like seeing "dead people" (from the movie)?  I can't imagine that 4th dimension, although, the math (tensors) is completely reasonable and valid.
