I'm really fuzzy right now, but here's a thread that might be helpful to you:
What makes an Introject?:
http://www.psychforums.com/dissociative-identity/topic106704.htmlI'm too fuzzy to think up the words I want to say, so I'll have to copy&paste from part of a reply of mine from the above thread if that's ok..
You can try to communicate with them just like any other alter, but be careful about it. I only say this because you'll want to prepare yourself for things you might hear, what they might say to you, how they might make you feel, etc. Because you can't let them get to you, or break you down, and you have to be prepared for what can come of interacting with them. That's all. Otherwise, go for communication. The more you can learn about this introject and understand why they do what they do, the better you'll be able to learn how to try and work with them and such.
Best of luck with everything.
