My examples are reading fiction and watching telly. Most of the time I think I use Fe, mostly to simulate having relationships. Sometimes I feel like a parasite, feeding off other people's emotions, just because of my own selfish needs, because I don't have those experiences but want them.
Of course, other functions are stimulated as well. Ni, for the patterns that emerge over seasons (I recently voiced my disappointment on some predictable pattern in some unrelated series), structures in storytelling and the like. But Ni is also stimulated by our imagination being incited when reading stories, especially in the fantasy genre, our picturing characters and their adventures, delving deep into their thoughts and living through them.
I have read somewhere that Ti is used the most when playing video games, which is an interesting thought, but I'd probably have to think on the matter before making a final judgement.
Se is obviously (to me) used when I actively do something in the present: playing or making music, sports or chores.
