That's a concept called Flow researched heavily by Mihaly Csikszentmihalyi
I highly recommend checking out his works to get through these fluffy blog posts into what the actual research says.

In a flow state you are, by definition, fully absorbed in an activity and are not necessarily very "self aware" in this kind of way.

Experiencing dhyāna is possible without achieving samadhi, but it is very unstable
Csikszentmihalyi flow state implies that one is involved in some activity, but in dhyānas you don't need to do anything.
