Events Tying Together

We met with Ireena and Ismark. Ismark would like us to escort his sister, Ireena, to a location as far away from Castle Ravenloft as possible. Upon further conversations with Ireena, we learned that Strahd has marked her twice already. The last time she was almost claimed, but he was interrupted. It seems that it happened the same time that he entered my dreams and saved me from my nightmare.
 
I still don't know what his intent is, but I feel like I'm going to need to watch myself when Ireena is near. We have both gained his attention for whatever reason. This is going to make things more difficult in the future.
