I'm playing an Oracle with Haunted Curse and Dark Tapestry.
However the DM and I changed the semantics a little and decided I wasnt in touch with beings from beyond space, but with ghosts and other beings on the ethereal plane.
No changes to the way powers work, we just changed the visual effect of some of them and the spells I cast.
Touch of Void, for eg, isnt the cold between stars but the cold of the grave.
Due to my affliation with ghosts, I've played a little bit crazy but in calm, listening to the other side before doing anything way. Some of my actions have unsettled the other party members.
Wierd things are further fueled by my having picked up a magic eye that allows me to see things that are really there (truesight), including into the Near Ethereal (does Near Ethereal exist in PF? It was a Ravenloft thing) so I see the ghosts all the time. When I appear to be talking to myself I am just being polite and talking to the ghosts around us.
The Haunting Curse, I decided, was very specifically my twin brother, who was still born, but has grown up with me anyway. My DM went with this with gusto and it has created some interesting encounters.
