Most of what we know about Arwen (Tolkien's Arwen, that is - not Peter Jackson's) comes from Appendix A,
The Tale of Aragorn and Arwen. It's definitely worth reading if you're interested in their story - one of my favorite passages (and the source for my forum nick [img]smilies/wink.gif[/img] ). We read that she apparently had some 'psychic' Elven abilities; at her first meeting with Aragorn, she predicted that her fate might be like that of Lúthien. Later, as Aragorn's betrothed, we are told:

Since we read of other Elves being able to communicate telepathically, this was nothing unusual. As to the gift of foresight, not only Elves, some humans, especially the Númenóreans, also had it.
