This is an elaborate description possibly alluding to complex feelings of uncertainty and mixed signals in a relationship, involving confusion ('guessing'), unease, abundant sparks (symbolizing attraction but not always positively), ambiguous relations between people. Overall, indicating complicated human emotions that don't have clear-cut definitions.
