Various forms of meditation are all about doing this Amy, in a variety of traditions.
The power of the mind and the extent of consciousness we can tap into is quite extraordinary. It takes a certain amount of dedication, practice and concentration however.
As Ailish says, mostly when caught up in day to day problems and adventures we don't take the time to explore these more subtle experiences.
All that said, we are here, incarnated in 3D reality to 'do stuff' - to have 3D-type reality experiences, birth, death, hunger, pain, thirst, love, desire and so on and to learn to deal with all that while still 'evolving' towards 'enlightenment' (or whatever it is one is up to).
In my view, if you spend your life in meditation, trying to tap into the 'other world' and tune out of 3D reality, you are kind of missing the point. So, balance is good - if you can 'be' in the world, but understand the complexities of reality at the same time and use these insights to further your own and others' earthly progress, perhaps that is using one's time wisely?
I am currently reading HH The Dalai Lama's book 'The universe in a single atom' and he talks about this at some length among other things. The intent of the book is to explore the similarities and differences in the Buddhist and Scientific world views regarding such things as the nature of reality and the purpose of existence. A good read.
